88X2222
Integrated Dual-port Multi-speed Ethernet Transceiver
with Electronic Dispersion Compensation Technology
Datasheet – Public
PRODUCT OVERVIEW
The Marvell® 88X2222 transceiver is a fully integrated
single chip solution providing end-to-end data
transmission over fiber-optic networks as well as
Twinax® copper links. It is a 2-port device that performs
all physical layer functions associated with 10GBASE-R,
and 1000BASE-X.
The Electronic Dispersion Compensation (EDC) engine
delivers high-speed bi-directional point-to-point full
duplex data transmission at 10.3 Gbps per port over a
variety of media. The performance of the engine can be
reduced to save power in fiber-optic applications that
does not require EDC.
The line-side interface supports 2 ports of 10GBASE-R
and 1000BASE-X. The line side also supports Clause 73
AP Auto-Negotiation.
The host-side interface supports 4 ports of 10GBASE-R,
RXAUI, 1000BASE-X, and 2 ports of XAUI. Any port
from the host side can be attached to any port on the line
side as long as the speeds match.
Features
Internal registers can be accessed via an MDIO/MDC
serial management interface which is compliant with the
IEEE 802.3 specification (Clause 45). The MDC
frequency supported is up to 25 MHz.

General Device Description
The line side and host side support various modes of operation for end-to-end data transmission
over multi-mode fiber, single mode fiber, and Twinax copper cables. The DSP engine overcomes the
impairments of the fiber cable, optical front end, and electrical interconnect.
Registers can be accessed by the host through standard clause 45 MDC/MDIO.
The device operates from a 1.0V digital core voltage and a 1.5V analog voltage. The digital I/O
signals can operate at 1.5V, 1.8V, 2.5V, and 3.3V.
Figure 1 shows a block diagram of the 88X2222 device.

Chip-level Functional Description
This section includes information on the following topics:
Section 3.1, Data Path
Section 3.2, Frequency Compensation FIFOs
Section 3.3, Resets
Section 3.4, Hardware Configuration
Section 3.5, MDC/MDIO Register Access
Section 3.6, GPIO and SFP+
Section 3.7, LED
Section 3.8, EEPROM Bridging and Polling
Section 3.9, Interrupt
Section 3.10, Power Management
Section 3.11, IEEE1149.1 and 1149.6 Controller
Section 3.12, Reference Clock
Section 3.13, Synchronous Ethernet Recovered Clocks
Section 3.14, Power Supplies
This section describes the chip-level functionality. Section 4, Line-side Description, on page 84 and
Section 5, Host-side Description, on page 93 describe the individual units in detail.
3.1
Data Path
Figure 4 illustrates the data path of both devices. This section examines the multiplexing in more
detail.
3.1.1
Cross Port Multiplexing
Although the device supports multiple different PCS with the various PCS attached to 1 or more
physical lanes, the device can be fundamentally viewed as 2 ports on the line side and 4 ports on the
host side. Any of the 2 ports on the line side can be attached to any of the 4 ports on the host side by
programming the cross port multiplexer. The association between the line and host side can be
independently programmed for ingress and egress paths and need not be the same for both
directions. It is also possible for data received on one port of the line (host) side to be transmitted out
on more than 1 port of the host (line) side.

The attached ports must run at the same speed (though the PCS types can be different). All speeds
are not supported on all ports. It is the user’s responsibility to ensure that the cross port multiplexing
is set correctly.
Registers 31.F400 bits 3:0 and 11:8 control which port on the host side attaches to ports 0 and 2 of
the line-side port transmitter respectively.
0000 = Power down the line-side port transmitter
0001 = Output idles on the line-side port transmitter
1000 = Attach to host-side port 0
1001 = Attach to host-side port 1
1010 = Attach to host-side port 2
1011 = Attach to host-side port 3
Registers 31.F401 bits 3:0, 7:4, 11:8, and 15:12 controls which port on the line side attaches to ports
0, 1, 2, and 3 of the host-side port transmitter respectively.
0000 = Power down the host-side port transmitter
0001 = Output idles on the host-side port transmitter
1000 = Attach to line-side port 0
1010 = Attach to line-side port 2
Registers 31.F400 and 31.F401 are global registers and can be accessed from port 0 PHYAD.

3.1.2
PCS Operational Mode and Lane Attachment
Each port supports multiple PCS. Not all PCS are supported by all ports. Only 1 PCS can be
enabled at a time for a given port, but different PCS can be selected among the different ports.
Since some PCS requires more lanes to operate than others, it is possible that conflicts can exist
(for example, Port 0 in XAUI mode conflicting with the other 3 ports). In case of conflict, the lower
numbered port will have the higher priority over the higher numbered port. The PCS on the port with
the lower priority that has conflict will be automatically powered down.
Register 31.F002.14:8 and 31.F002.6:0 selects the PCS type for the line and host side, respectively.
Not all PCS type are available for each port. Table 13 lists out which PCS is available for each port.
Table 14 and Table 15 list the pin mappings for PCS modes for the line and host interfaces. Table 16
and Table 17 list the valid 7 bit setting for registers 31.F002.14:8 and 31.F002.6:0.

Resets
A hardware reset (RESETn) resets the entire chip and initializes all the registers to their hardware
reset default.
A software reset has a similar effect on the affected units as a hardware reset except all Retain type
of registers hold their value, and any previously written values in the ‘Update’ registers take effect.
To assert a host-/line-side port reset, set:
31.F003.15 to 1 for line side of the port
31.F003.7 to 1 for host side of the port
Refer to Section 4.5, Power Management, on page 88 for the line-side PCS and PMA resets, and
Section 5.5, Power Management, on page 96 for the host-side PCS and PMA resets.

MDC/MDIO Register Access
The management interface provides access to the internal registers via the MDC and MDIO pins
and is compliant with IEEE 802.3 clause 45. MDC is the management data clock input and, it can
run from DC to a maximum rate of 25 MHz. At high, MDIO fanouts the maximum rate may be
decreased depending on the output loading. MDIO is the management data input/output and is a
bi-directional signal that runs synchronously to MDC.
The MDIO does not require a pull-up resistor. If another open-drain device driving MDIO requires a
pull-up resistor, it should drive or be pulled up to the same voltage value as the DVDDIO rail.

The MDIO implements a 16-bit address register that stores the address of the register to be
accessed. For an address cycle, it contains the address of the register to be accessed on the next
cycle. For read, write, post-read-increment-address cycles, the field contains the data for the
register. At power up and reset, the contents of the register are undefined.
Write, read, and post-read-increment-address frames access the address register, though write and
read frames do not modify the contents of the address register.

High-Speed MDC/MDIO Management Interface Protocol
In addition to supporting the typical MDC/MDIO protocol, the device has the capability to run MDC
as fast as 40 MHz. Write operation can operate normally at this speed; however, for read operation,
the MDC clock cycle must be slowed down for the TA period as shown in the Figure 8.
During read operations, the MDC clock must slow down so that the PHY has enough time to fetch
the data. There are 2 scenarios. In 1 scenario, the MDIO has exclusive access to the internal
register bus.
For timing details, see Table 345 on page 233.

3.6.1
Enabling GPIO Functionality
The TX_DISABLED, TOD, MPC, LED1, and LED0 pins operates in the LED mode unless register
31.F016.4:3 is set to 01, and 31.F014.11, 31.F014.7, 31.F015.15, 31.F015.11, 31.F015.7, 31.F015.3
respectively are set to 1. Once set to 1, the LED pins can be controlled via the GPIO registers.
The SCL and SDA pins operate in the TWSI mode unless register 31.F016.15 and 31.F016.11
respectively are set to 1. Once set to 1, the SCL and SDA pins can be controlled via the GPIO
registers.
The GPIO, RX_LOS, TX_FAULT, and MOD_ABS pins can always be controlled via the GPIO
registers.
3.6.2
Controlling and Sensing
Register 31.F013 controls whether the GPIO pins are inputs or outputs. Each pin can be individually
controlled.
Register 31.F012 allows the pins to be controlled and sensed.
When configured as input, a read to register 31.F012 will return the real-time sampled state of the
pin at the time of the read. A write will write the output register but has no immediate effect on the pin
since the pin is configured to be an input. The input is sampled once every 38.4 ns.
When configured as output, a read to register 31.F012 returns the value in the output register. A
write writes the output register which in turn drives the state of the pin.

GPIO Interrupts
When the pins are configured as input, several types of interrupt events can be generated. Registers
31.F014, 31.F015, and 31.F016 allow each pin to be configured to generate interrupt on 1 of 5 types
of events:
Low Level
High Level
High to Low Transition
Low to High Transition
Transitions on Either Edge
The interrupt generation can also be disabled.
When an interrupt event is generated, it is latched high in register 31.F011. The register bits will
remain high until read.
The INT pin can be asserted when interrupt events occur. Register 31.F010 sets the interrupt

pin will assert.
If any of the following occur, no new interrupt events will be generated and reported in register
31.F011 for that particular pin:
When a pin is set to output
When TX_DISABLED, TOD, MPC, LED1, and LED0 are set to LED function instead of GPIO
function
When SCL and SDA are set to TWSI function instead of GPIO function

If a previous interrupt event occurred but is not read, the register will retain its value until read. In
other words, if an interrupt event occurred while the pin is configured as an input, the interrupt status
bit will be set. If subsequently the pin is set to an output, the interrupt status bit will remain set until it
is read.
When changing a pin from output to input, an edge triggered event will not be generated on the
transition. For example, if the pin is configured as an output and is driven low and there is a pull-up
attached to the pin. Once the pin is configured as an input (to tri-state the pin), there will be a low to
high transition. This low to high transition will not trigger an edge event. Subsequent transitions with
the pin configured as input will trigger edge events.

3.6.4.1
TX_DISABLE
When register 31.F016.4:3 of a port is set to 10, the TX_DISABLE has the following behavior.
The TX_DISABLE pin is configured as an output and writing to registers 31.F010.8, 31.F012.8, and
31.F013.8 has no effect.
If the PCS of port N is configured to 1000BASE-X or 10GBASE-R then
TX_DISABLE[N] pin is set high when port N register 1.0009.0 is set to 1 or 1.0009.1 is set to 1.
Otherwise TX_DISABLE[N] pin is set low.
Note that the PCS transmit path is also disabled when the transmit disable bits are set in register
1.0009.

3.6.4.2
RX_LOS
When 31.F014.11 is set to 0 the RX_LOS pin is configured as an input and writing to register
31.F013.2 has no effect. The RX_LOS is used in conjunction with the receiver status of the lane to
determine signal detect. Both the RX_LOS and the receiver must detect a signal for signal detect to
be up. When 31.F014.11 = 1, then RX_LOS is not used to determine signal detect and only the
receiver status of the lane is used to determine signal detect status.
Port N register 31.F012.2 will report the state of RX_LOS[N], and 31.F011.2 will report the interrupt
status of RX_LOS[N] regardless of the setting of register 31.F014.11.
When register 31.F014.11 of a port is set to 0, the RX_LOS has the following behavior that is
dependent on the PCS.
If the PCS of port N is configured to 1000BASE-X or 10GBASE-R then
RX_LOS[N] pin is used for lane 0 signal detect, and port N register 1.000A.0 and 1.000A.1
reflects the signal detect status.
3.6.4.3
TX_FAULT
When 31.F014.7 is set to 0, the TX_FAULT pin is configured as an input and writing to register
31.F013.1 has no effect. The TX_FAULT pin is used to determine the state of the transmit fault
register 1.0008.11. When 31.F014.7 = 1, then register 1.0008.11 is always set to 0.
Port N register 31.F012.1 will report the state of TX_FAULT[N], and 31.F011.1 will report the
interrupt status of TX_FAULT[N] regardless of the setting of register 31.F014.7.
When register 31.F014.7 of a port is set to 0, the TX_FAULT has the following behavior that is
dependent on the PCS.
If the PCS of port N is configured to 1000BASE-X or 10GBASE-R then
Port N register 1.0008.11 is set to 1 when TX_FAULT[N] is high. Otherwise register 1.0008.11 is
set to 0.

LED
The TX_DISABLED, TOD, MPC, LED1, and LED0 pins can be used to drive LED pins. Registers
31.F020 through 31.F027 control the operation of the LED pins. TX_DISABLED, TOD, MPC, LED1,
and LED0 will operate per this section unless the pin is used for GPIO purposes (see Section 3.6,
GPIO and SFP+, on page 48).

LED Polarity
There are a variety of ways to hook up the LEDs. Some examples are shown in Figure 10. In order
to make things more flexible registers 31.F020.1:0, 31.F021.1:0, 31.F022.1:0, 31.F023.1:0, and
31.F024.1:0 specify the output polarity for the LED function. The lower bit of each pair specified the
on (active) state of the LED, either high or low. The upper bit of each pair specifies whether the off
state of the LED should be driven to the opposite level of the on state or Hi-Z.

Pulse Stretching and Blinking

3.7.3
Bi-Color LED Mixing
In the dual LED modes, the mixing function allows the 2 colors of the LED to be mixed to form a third
color. Register 31.F026.7:4 control the amount to mix in the TOD and LED1 pins. Register
31.F026.3:0 controls the amount to mix in the MPC and LED0 pins. The mixing is determined by the
percentage of time the LED is on during the active state. The percentage is selectable in 12.5%
increments.
There are 2 types of bi-color LEDs: 3 terminal type, and 2 terminal type. For example, the third and
fourth LED block from the left in Figure 10 illustrate 3 terminal types, and the one on the far right in
Figure 10 illustrate 2 terminal type. In the 3 terminal type both of the LEDs can be turned on at the
same time. Hence the sum of the percentage specified by 31.F026.7:4 and 31.F026.3:0 can exceed
100%. However, in the 2 terminal type, the sum should never exceed 100% since only 1 LED can be
turned on at any given time.
The mixing only applies when register 31.F020.11:8 or 31.F022.11:8 are set to 101x. There is no
mixing in single LED modes.

EEPROM Bridging and Polling
The 88X2222 device supports the ability to cache the contents of the EEPROM into an onboard
RAM for faster read access. The device has the ability to periodically read the EEPROM and refresh
the RAM. The 88X2222 device can also act as a bridge so that the EEPROM or other devices can
be accessed via the MDC/MDIO interface of the PHY.
The EEPROM or external device is attached to the Two-wire Serial Interface (TWSI) via the SCL and
SDA pins.
Register 1.8000.10 can be set to 1 to force the TWSI to reset.

Bridging Function
The bridging function allows the contents of the EEPROM to be accessed directly via the
MDC/MDIO. The access is through a series of reads and writes to the PHY register. Note that the
access is not limited to the EEPROM but also to any device that is attached to the TWSI.
Since other devices may be connected to the TWSI where the slave address is not necessarily
1010xxx, there is a hook to access the TWSI device directly from the MDIO. Registers 1.8001,
1.8002, and 1.8003 give direct access between the MDIO and the TWSI.

Register 1.8002.10:8 is the status in response to setting to
writing register 1.8001.
RO, LH
Register 1.8002.10:8 will remain at 010 until the command is
completed. Once the command is completed, the status 001,
011, 100, 101, or 111 will remain until register 1.8002 is read.
The register will clear on read.
If a new command is issued by writing register 1.8001 without
reading register 1.8002 for a previous command, the status of
the previous command will be lost.
If a command initiated by writing register 1.8001 is still in
progress and a second command is issued, the status
1.8002.10:8 will reflect the first command.
The second command is ignored but register 1.8002.10:8 will
not be set to 111.
Command Done - No Error is set when the TWSI slave
properly responds with ACK.
In the case of a write command with automatic read back, a
Command Done - No Error status will be returned even if the
read back data does not match the written data or if the TWSI
slave does not respond with ACK during the read back.
Register 1.8002.7:0 is valid only when register 1.8002.10:8 is

Read from TWSI Slave Device to the MDIO
When a read operation to the TWSI is required, the slave address and byte address is written to
register 1.8001.15:9 and 1.8001.7:0 respectively with register 1.8001.8 set to 1 indicating read.
Once register 1.8001 is written, a read operation on the TWSI commences only if the TWSI is free;
otherwise, a read operation on the TWSI is never issued. The byte that is read is stored in register
1.8002.7:0. The status of the read operation is stored in register 1.8002.10:8.
While the read operation is pending register 1.8002.10:8 is set to 010. Once the read operation is
completed and the TWSI slave sends all acknowledges register 1.8002.10:8 is set to 001 indicating
the read operation completed without error. A 101 is returned if the read command is aborted when
the TWSI slave does not acknowledge properly. A 111 is returned if the TWSI is busy when register
1.8001 was written.
Note that other than the 010 setting (command in progress) a read to 1.8002 will cause bits 10:8 to
clear to 000.
3.8.1.2
Write from MDIO into the TWSI Slave Device
Write commands into the EEPROM are always available through the MDIO. If write access should
be disabled, the EEPROM itself should be configured to ignore write commands from the 88X2222
device.
When a write operation to the TWSI is required, the byte data should first be written into 1.8003.7:0.
The slave address and byte address is written to register 1.8001.15:9 and 1.8001.7:0 respectively
with register 1.8001.8 set to 0 indicating write. Once register 1.8001 is written a write operation to
the TWSI commences. If the read back bit is set in register 1.8003.9 then a read operation to the
same address is performed after the write. The byte that is read is stored in register 1.8002.7:0.
The status of the write operation is stored in register 1.8002.10:8.
While the write operation is pending register 1.8002.10:8 is set to 010. Once the write operation is
completed and, optionally, the read back command and the TWSI slave sends all acknowledges,
register 1.8002.10:8 is set to 001 indicating the write operation completed without error. A 011 is
returned if the write operation is successfully completed but the read back command is aborted. A
101 is returned if the write command is aborted when the TWSI slave does not acknowledge
properly. A 111 is returned if the TWSI is busy when register 1.8001 was written. Note that other than
the 010 setting (command in progress) a read to 1.8002 will cause bits 10:8 to clear to 000.
Since it may take some time for the write to take effect in the external device, the 88X2222 device
should wait for some amount of time as programmed in register 1.8003.15:12 after the write
operation before issuing a read back command.

EEPROM Bridging and Polling
3.8.2
EEPROM Caching into RAM
The contents of the EEPROM or other device on the TWSI can be cached into on-chip memory.
There are 2 segments of 128 bytes that can be cached. The first 128 byte segment is referred to as
the A0 page and the second 128 byte segment is referred to as the secondary page.
Table 37, Table 38, and Table 39 list all the caching and polling registers. The A0 page always has a
slave address of 1010000 and always reads the lower 128 bytes of the device. The A0 page control
registers are located in 1.8000.1:0, the status registers located in 1.8000.3:2 and 1.8000.9, and the
128 bytes are stored in 1.8007 to 1.8086 bits 7:0.
The secondary page has similar registers located in 1.8000.12:11, 1.8000.14:13, 1.8000.15, and
1.8087 to 1.8106 bits 7:0 respectively. The only exception for the secondary page is that the slave
address is not fixed and can be specified in 1.8004.7:1, and 18004.0 specifies whether the upper or
lower 128 bytes of the device is read.
The caching sequence is not triggered at the de-assertion of hardware reset. Instead, the EEPROM
is read, and RAM is loaded every time the MOD_ABS pin makes a high to low transition. The
caching sequence takes place after a delay specified by register 1.8004.15:13. The A0 page is
cached on MOD_ABS high to low transition only if 1.8000.1:0 is set to 01 or 10. The secondary page
is similarly cached only if 1.8000.12:11 is set to 01 or 10. If caching is enabled for both pages, then
page A0 is always loaded first.
Note that if the TWSI is active for any reason when the MOD_ABS pin is triggered, the caching
sequence will be deferred until the TWSI is inactive. If the TWSI is in the middle of a caching
sequence initiated by the user (see below) the current caching sequence will be aborted after the
completion of the active TWSI transaction and a new caching sequence is then started.
Either or both RAM caches are periodically updated if register 1.8000.1:0 and/or 1.8000.12:11 are
set to 10. The update period is specified by register 1.8004.10:9. If both caches are to be updated
the A0 page gets updated first. The polling will continue until it is disabled via registers 1.8000.1:0 or
1.8000.12:11. Alternatively, if the MOD_ABS pin goes high, the polling will stop immediately after the
TWSI transaction completes.
The contents of the EEPROM can be reloaded into RAM by writing register 1.8000.1:0 and/or
1.8000.12:11 to 11. These bits are self-clearing. If both 1.8000.1:0 and 1.8000.12:11 are set to 11
concurrently, the A0 page will be serviced first and, upon completion, 1.80001:0 will be cleared and
then the secondary page will be serviced. Manual loading can be initiated regardless of the state of
the MOD_ABS pin. The result of the reload can be read via register 1.8000.3:2, 1.8000.9 or
1.8000.14:13, 1.8000.15.
All single byte read/write commands are deferred when initiated in the middle of an RAM update
cycle.
Once the caching sequence is completed, the status register in 1.8000.3:2 or 1.8000.14:13 will be
updated. Registers 1.8000.3:2 and 18000.14:13 are clear on read registers. After reading, the bits
clear to 00. The status registers are updated according to the following priority.
1. If the entire 128 bytes have been updated successfully at least once since the last read to
register 1.8000, then the status bits will be set to 01.
2. If all attempts to read the entire 128 bytes have failed since the last read to register 1.8000, then
the status bits will be set to 11. A fail is defined to have occurred if any of the 128 byte reads
return error.
3. If the circuit is in the middle of the first attempt to update the 128 bytes since the last read to
register 1.8000, then the status will return 10.
4. If the circuit never made an attempt to update the 128 byte registers since the last read to
register 1.8000, then the status will return 00.

Whenever MOD_ABS pin transitions from 0 to 1 or whenever software or hardware reset is
asserted, then 1.8000.9 and 1.8000.15 are set to 0s. If 1 successful caching sequence completes,
then 1.8000.9 or 1.8000.15 will be set to a 1 and remains set until MOD_ABS transitions from 0 to 1
or until a software or hardware reset is issued. Once the status bit is set to 1, it will remain set even
if subsequent updates are not successful.
The maximum size EEPROM for each segment that can be handled is 128 bytes. The expected
device type and device page selection in the slave address of the EEPROM is 1010000 for the A0
page. Any other value will result in the EEPROM not being read. Note that other pages can be read
by setting registers 1.8004.7:1 and 1.8004.0.
The RAM can be access via reading Registers 1.8007 to 1.8086 bits 7:0 for the A0 page and 1.8087
to 1.8106 bits 7:0 for the secondary page.
The RAM is protected by an Error Correction Circuit (ECC) that generates 2 status signals, 1 to
indicate a single bit error has been corrected and another to indicate uncorrectable bit errors. These
2 signals are used to generate interrupts. Registers 1.8004.12:11 are the interrupt enable bits and
1.8002.12:11 are the interrupt status bits. The interrupt status bits latch high when the status bits
assert. The bits clear on read.

Interrupt
Various functional units in the device can generate interrupt on the INTn pin. INTn is pulled low when
an enabled interrupt is active.
The interrupt status is reported upwards via 3 levels:
First level (information purposes only) — Reports which port is generating an active interrupt
Second level — Reports which function in the port is generating the interrupt
Third level — Interrupt registers report the actual interrupt status
The third level interrupt status and the corresponding enables are described in the register sections
for each function and in the following interrupt tree diagrams. The polarity of the interrupt can be
controlled by Register 31.F421.

Power Management
The chip can be globally set to be in the power down state after hardware reset. See Section 3.4,
Hardware Configuration, on page 46 on how to configure the device in the power down state.
The line and host can be manually powered down as described in Section 4.5, Power Management,
on page 88 and Section 5.5, Power Management, on page 96 respectively.
They can also be powered up and down via a single write to register 31.F403.7:0. There are many
registers that can be used to power down various blocks (for example, 31.F403.7:0 registers in
Section 4.5, Power Management, on page 88 and Section 5.5, Power Management, on page 96).
All registers associated with a block must be powered for it to be active.

IEEE1149.1 and 1149.6 Controller
The IEEE 1149.1 standard defines a test access port and boundary-scan architecture for digital
integrated circuits and for the digital portions of mixed analog/digital integrated circuits. The IEEE
1149.6 standard defines a test access port and boundary-scan architecture for AC coupled signals.
This standard provides a solution for testing assembled printed circuit boards and other products
based on highly complex digital integrated circuits and high-density surface-mounting assembly
techniques.
The 88X2222 device implements the instructions shown in Table 43. Upon reset, ID_CODE
instruction is selected. The instruction opcodes are shown in Table 43.

The 88X2222 device reserves 5 pins called the Test Access Port (TAP) to provide test access: Test
Mode Select Input (TMS), Test Clock Input (TCK), Test Data Input (TDI), and Test Data Output
(TDO), and Test Reset Input (TRSTn). To ensure race-free operation all input and output data is
synchronous with the test clock (TCK). TAP input signals (TMS and TDI) are clocked into the test
logic on the rising edge of TCK while output signal (TDO) is clocked on the falling edge. For
additional details, refer to the IEEE 1149.1 Boundary Scan Architecture document.
3.11.1
BYPASS Instruction
The BYPASS instruction uses the bypass register. This register contains a single shift-register stage
and is used to provide a minimum length serial path between the TDI and TDO pins of the 88X2222
device when test operation is not required. This arrangement allows rapid movement of test data to
and from other testable devices in the system.

3.11.2
SAMPLE/PRELOAD Instruction
The SAMPLE/PRELOAD instruction enables scanning of the boundary-scan register without
causing interference to the normal operation of the 88X2222 device. Two functions are performed
when this instruction is selected: sample and preload.
Sample allows a snapshot to be taken of the data flowing from the system pins to the on-chip test
logic or vice versa, without interfering with normal operation. The snapshot is taken on the rising
edge of TCK in the Capture-DR controller state, and the data can be viewed by shifting through the
component's TDO output.
While sampling and shifting data out through TDO for observation, preload enables an initial data
pattern to be shifted in through TDI and to be placed at the latched parallel output of the
boundary-scan register cells that are connected to system output pins. This step ensures that known
data is driven through the system output pins upon entering the extest instruction. Without preload,
indeterminate data would be driven until the first scan sequence is complete. The shifting of data for
the sample and preload phases can occur simultaneously. While data capture is being shifted out,
the preload data can be shifted in.
The boundary scan register for MIN[7] is closest to TDO.

EXTEST Instruction
The EXTEST instruction enables circuitry external to the 88X2222 device (typically the board
interconnections) to be tested. Prior to executing the EXTEST instruction, the first test stimulus to be
applied is shifted into the boundary-scan registers using the sample/preload instruction. Thus, when
the change to the extest instruction takes place, known data is driven immediately from the 88X2222
to its external connections. Note that the SERDES output pins will be driven to static levels. The
positive and negative legs of the SERDES output pins are controlled via a single boundary scan
cell.The positive leg outputs the level specified by the boundary scan cell while the negative leg
outputs the opposite level.
3.11.4
CLAMP Instruction
The CLAMP instruction enables the state of the signals driven from component pins to be
determined from the boundary-scan register while the bypass register is selected as the serial path
between TDI and TDO. The signals driven from the component pins do not change while the clamp
instruction is selected.
3.11.5
HIGH-Z Instruction
The HIGH-Z instruction places all of the digital component system logic outputs in an inactive
high-impedance drive state. In this state, an in-circuit test system may drive signals onto the
connections normally driven by a component output without incurring the risk of damage to the
component.
The SERDES outputs cannot be tri-stated.

EXTEST_PULSE Instruction
When the AC/DC select is set to DC, the EXTEST_PULSE instruction has the same behavior as the
EXTEST instruction.
When the AC/DC select is set to AC, the EXTEST_PULSE instruction has the same behavior as the
EXTEST instruction except for the behavior of the SERDES output pins.
As in the EXTEST instruction, the test stimulus must first be shifted into the boundary-scan registers.
Upon the execution of the EXTEST_PULSE instruction the SERDES positive output pins output the
level specified by the test stimulus and SERDES negative output pins output the opposite level.
However, if the TAP controller enters into the Run-Test/Idle state the SERDES positive output pins
output the inverted level specified by the test stimulus and SERDES negative output pins output the
opposite level.
When the TAP controller exits the Run-Test/Idle state, the SERDES positive output pins again output
the level specified by the test stimulus and SERDES negative output pins output the opposite level.
3.11.8
EXTEST_TRAIN Instruction
When the AC/DC select is set to DC, the EXTEST_TRAIN instruction has the same behavior as the
EXTEST instruction.
When the AC/DC select is set to AC, the EXTEST_TRAIN instruction has the same behavior as the
EXTEST instruction except for the behavior of the SERDES output pins.
As in the EXTEST instruction, the test stimulus must first be shifted into the boundary-scan registers.
Upon execution of the EXTEST_PULSE instruction, the SERDES positive output pins output the
level specified by the test stimulus and SERDES negative output pins output the opposite level.
However, if the TAP controller enters into the Run-Test/Idle state, the SERDES output pins will
toggle between inverted and non-inverted levels on the falling edge of TCK. This toggling will
continue for as long as the TAP controller remains in the Run-Test/Idle state.
When the TAP controller exits the Run-Test/Idle state, the SERDES positive output pins again output
the level specified by the test stimulus and SERDES negative output pins output the opposite level.
3.11.9
AC-JTAG Fault Detection
The fault detection across AC coupled connections can be detected with a combination of (DC)
EXTEST and any one of the AC JTAG commands. The AC coupled connection is shown in
Figure 19. The fault signature is shown in Table 46.
Column 1 lists the fault type.
Columns 2 to 5 list the behavior when both the transmitter and receiver are running the
EXTEST_TRAIN and EXTEST_PULSE commands.
• Column 2 shows the expected value captured by the boundary scan cell that is connected to
the test receiver, which is connected to the positive input when a negative differential pulse is
transmitted.

• Column 3 is the same as column 2 except for the negative input.
• Columns 4 and 5 are similar to columns 2 and 3 except a positive differential pulse is
transmitted.
Columns 6 to 9 is similar to columns 2 to 5 except both the transmitter and receiver are running
the (DC) EXTEST command.
While it is not possible to identify precisely which fault is occurring based on the fault signature, the
signature to the no fault condition is unique when the (DC) EXTEST command is run with at least 1
of the EXTEST_TRAIN, or EXTEST_PULSE commands. Note that running only AC JTAG
commands is not sufficient since the no fault condition signature is not distinguishable from the Tx to
Rx short (see shaded cells in Table 46).

NOTES:
1. Short on positive and negative leg can have several behavior on the test receiver. If both drivers cancel each other
out then output on both legs is 0. If one driver dominates the other then both legs are either both 1 or both 0. In any
case, the result is that both legs will have same value.
2. A solid short to power is assumed. If the short has high inductance then a pulse may still be sent at the receiver and
will be mistaken as a good connection.

NOTES:
1. Short on positive and negative leg can have several behaviors on the test receiver. If both drivers cancel each other
out then output on both legs is 0. If one driver dominates the other then both legs are either both 1 or both 0. In any
case, the result is that both legs will have same value.
2. A solid short to power is assumed. If the short has high inductance then a pulse may still be sent at the receiver and
will be mistaken as a good connection.

Reference Clock
An external oscillator provides a reference for the on-board transmit Phase Lock Loop (PLL) and
clock generation block that provides internal clocks for both the transmit and receive data paths. The
clock input pins are CLKP/CLKN.
CLKP/CLKN runs on a 156.25 MHz differential clock. The FREQ_SEL[1:0] should be set to 00.
3.13

VDDO
There are 4 separate VDDO segments (VDDOT, VDDOS, VDDOL, and VDDOM). Each segment
can be independently set to 1 for the following voltages: 1.2V, 1.5V, 1.8V, 2.5V, or 3.3V. Each VDDO
segment has a corresponding voltage select configuration pin (VSEL_T, VSEL_S, VSEL_L, and
VSEL_M). Table 48 lists the signals under each of the VDDO segments.
If the VDDO* segment is set to 1.2V, 1.5V, or 1.8V then its corresponding VSEL_* should tied to
VDDO*.
If the VDDO* segment is set to 2.5V, or 3.3V then its corresponding VSEL_* should tied to VSS.
The input pins are not high voltage tolerant. For example if VDDOT is tied to 2.5V then RESETn
should not be driven to 3.3V.

Line-side Description
This section includes information on the following topics:
Section 4.1, Media Electrical Interface
Section 4.2, PCS
Section 4.3, Loopback
Section 4.4, Synchronization FIFO
Section 4.5, Power Management
Section 4.6, Traffic Generation and Checking
Section 4.7, PRBS and Pattern Generators
Section 4.8, Interrupt
The line-side interface is comprised of 2 differential input lanes NIP[0], NIP[2]/NIN[0], NIN[2], and 2
differential output lanes NOP[0], NOP[2]/NON[0], NON[2]. They can operate over multimode fiber,
single mode fiber, and Twinax copper cables. The DSP engine overcomes the impairments of the
fiber cable, optical front end, and electrical interconnect. In this document, each set of input/output
lanes is referred to as lane N0 and N2.
These lanes can be arranged to form 2-ports of 1000BASE-X and 10GBASE-R.
4.1
Media Electrical Interface
The input and output buffers of the SERDES interface are internally terminated by 50Ω impedance
(100Ω differential). No external terminations are required.
The SERDES transmitter uses a 3 tap (1 pre-tap and 1 post-tap) FIR filter that is implemented for the
purpose of channel equalization. The FIR tap values can be manually adjusted to optimize the
transmit eye over a particular channel.
The SERDES receiver contains a DSP-based Electronic Dispersion Compensation engine to
perform clock and data recovery that significantly exceed the receiver performance specified by the
10GBASE-LRM standard. Advanced algorithms enables operation over multi-mode fiber.
The Electronic Dispersion Compensation can be disabled when not needed to trade performance
versus power and latency.
4.2
PCS
Each port supports a multiple number of different PCS. Section 3.1.2, PCS Operational Mode and
Lane Attachment, on page 42 describes how to configure each port for the various PCS. This
section focuses on the PCS itself.
4.2.1
10GBASE-R
The 10GBASE-R PCS is available on all ports. Lanes N0 and N2 are used by port 0 and 2
respectively. It is enabled by setting register 31.F002.14:8 to 0x71.
The 10GBASE-R PCS operates according to Clause 49 of the IEEE 802.3ae specification. The PCS
uses a 64B/66B coding and scrambling to improve the transmission characteristics of the serial data
and ease clock recovery at the receiver. The synchronization headers for 64B/66B code enable the
receiver to achieve block alignment on the receive data. For details, refer to the IEEE 802.3
specification.

1000BASE-X
The 1000BASE-X PCS is available on all ports. Lanes N0 and N2 are used by port 0 and 2,
respectively. There are several modes of 1000BASE-X. It is enabled by setting register
31.F002.14:8 to 1 for the following values.
0x7A = 1000BASE-X, 1000BASE-X Auto-Negotiation off
0x7B = 1000BASE-X, 1000BASE-X Auto-Negotiation on
0x7C = SGMII (system), SGMII Auto-Negotiation off

0x7E = SGMII (media), SGMII Auto-Negotiation off
0x7F = SGMII (media), SGMII Auto-Negotiation on
4.2.2.1
PCS
The 1000BASE-X PCS operates according to Clause 36 of the IEEE 802.3 specification. The PCS
uses a 8/10 bit coding for DC line balancing. For further details refer to the IEEE 802.3 specification.
The SGMII protocol is also supported over 1000BASE-X. The SGMII allows 10Mbps, 100Mbps, and
1000Mbps throughput over 1000BASE-X line coding.
When SGMII Auto-Negotiation is turned off (3.2000.12 = 0), the speed setting is programmed via
register 3.2000 bits 13 and 6. Link is established when the underlying 1000BASE-X establishes link.
When SGMII Auto-Negotiation is turned on(3.2000.12 = 1) and the SGMII is set to the media side,
the speed setting is programmed via register 3.2000 bits 13 and 6. This speed capability is
advertised and Auto-Negotiations have to complete prior to link being established.
When SGMII Auto-Negotiation is turned on (3.2000.12 = 1) and the SGMII is set to the system side,
the speed setting is determined by the Auto-Negotiation speed advertised by the link partner.
Auto-Negotiations must be complete prior to link being established.
Although register 31.F002.14:8 can set the Auto-Negotiation to be on or off, that setting can be
overridden by writing register 3.2000.12.
The SGMII mode is intended to be operated in pairs. In general, the port on the line side will be set
to SGMII system while the attached port on the host side set to SGMII media, though it is possible to
reverse this. If SGMII Auto-Negotiation is turned on, the Auto-Negotiation results on the SGMII
system on the line side will be passed to the SGMII media on the host side which will in turn
advertise the results.

4.2.2.2
1000BASE-X Auto-Negotiation
1000BASE-X Auto-Negotiation is defined in Clause 37 of the IEEE 802.3 specification. It is used to
auto-negotiate duplex and flow control over fiber cable. Registers 3.2000, 3.2004, 3.2005, 3.2006,
3.2007, 3.2008, and 3.200F are used to enable Auto-Negotiation, advertise capabilities, determine
link partner’s capabilities, show Auto-Negotiation status, and show the duplex mode of operation
respectively.
The device supports Next Page option for 1000BASE-X Auto-Negotiation. Register 3.2007 of the
fiber pages is used to transmit Next Pages, and register 3.2008 of the fiber pages is used to store
the received Next Pages. The Next Page exchange occurs with software intervention. The user must
set Register 3.2004.15 to enable fiber Next Page exchange. Each Next Page received in the
registers should be read before a new Next Page to be transmitted is loaded in Register 3.2007.
If the PHY enables 1000BASE-X Auto-Negotiation and the link partner does not, then the link cannot
be established. The device implements an Auto-Negotiation bypass mode. See Section 4.2.2.4,
Auto-Negotiation Bypass Mode, on page 87 for details.
4.2.2.3
SGMII Auto-Negotiation
SGMII is a de-facto standard designed by Cisco. SGMII uses 1000BASE-X coding to send data as
well as Auto-Negotiation information between the PHY and the MAC. However, the contents of the
SGMII Auto-Negotiation are different than the 1000BASE-X Auto-Negotiation. See the “Cisco SGMII
Specification” and the “MAC Interfaces and Auto-Negotiation” application note for further details.
The device supports SGMII with and without Auto-Negotiation. Auto-Negotiation can be enabled or
disabled by writing to Register 3.2000.12 followed by a soft reset. If SGMII Auto-Negotiation is
disabled, the MAC interface link, speed, and duplex status (determined by the media side) cannot be
conveyed to the MAC from the PHY. The user must program the MAC with this information in some
other way (for example, by reading PHY registers for link, speed, and duplex status).
The SGMII Auto-Negotiation information flow is shown in Figure 22.

4.2.2.4
Auto-Negotiation Bypass Mode
If the MAC or the PHY implements the Auto-Negotiation function and the link partner does not,
two-way communication is not possible unless Auto-Negotiation is manually disabled and both sides
are configured to work in the same operational modes. To solve this problem, the device implements
the SGMII Auto-Negotiation Bypass Mode. When entering the state “Ability_Detect”, a bypass timer
begins to count down from an initial value of approximately 200 ms. If the device receives idles
during that 200 ms, the device will interpret that the other side is “alive” but cannot send
configuration codes to perform Auto-Negotiation. After the 200 ms timeframe, the state machine will
move to a new state called “Bypass_Link_Up” in which the device assumes a link-up status and the
operational mode is set to the value listed under the Comments column of Table 49.

FIFO
Synchronization FIFO
Each port has a transmit synchronizing FIFOs to reconcile frequency differences between the clocks
of the internal bus and the clock used to transmit data onto the media interface. The depth of the
FIFO can be programmed by setting Register 3.F00C.15:14.
The FIFO depths can be increased in length to support longer frames. The device has settings for
maximum frame sizes of 10 Kb, 20 Kb, 40 Kb, and 80 Kb with up to ±100 ppm clock jitter in 10 Gbps
operation and 10 Kb, 15 Kb, 20 Kb, and 25 Kb with up to ±100 ppm clock jitter in 1 Gbps operation.
The deeper the FIFO depth, the higher the latency will be.
The FIFO overflow/underflow status is reported in Register 3.F00B.1:0.
4.5
Power Management
The 88X2222 device will automatically power down unused circuits. The media side can be forced
into a power down state by setting 1.0000.11, 2.0000.11, 3.0000.11, 3.1000.11, 3.2000.11, or
3.3000.11 to 1. Note that these power down registers are physically the same bit even though they
reside in different locations. Port level register, 31.F003.14 can also be used to power down the
media side. Since 31.0xF003.14 is physically a separate register bit, setting this bit won't be
reflected into PCS power down bits as previously mentioned, but will override them.
To soft reset the media side set registers 1.0000.15, 2.0000.15, 3.0000.15, 3.1000.15, 3.2000.15,
3.3000.15, or 7.0000.15 to 1. Register 31.F003.15 can also be used to soft reset the media side.
These software reset registers are physically the same bit even though they reside in different
locations.

Traffic Generation and Checking
4.6
Traffic Generation and Checking
This section describes the Generator/Checker functions. All counters are 48 bits long. If Register
3.F010.14 is set to 1, the counters clear on read. If Register 3.F010.14 is set to 0, the counters will
keep counting unto 3.F010.6 is set to 1 to clear the contents.
4.6.1
Packet Generator
A packet generator enables the device to generate traffic onto the media without the need to receive
data from the host.
Register 3.F010.1 enables the internal packet generator.
Register 3.F016 specifies the number of bytes in the packet that is to be generated. This count
includes the frame bytes but does not include the 4-byte CRC (unless it is appended - Register
3.F011.3 = 0), the terminate symbol, nor the 8 preamble bytes. If the register is set to 0x0000 then
the length will be randomly selected between 64 to 1518 bytes. If the register is set to 0x0001 then
the length will be randomly selected to be between 64 to 0x0FFF bytes, 0x0002 then 64 to 0x1FFF
bytes, 0x0003 then 64 to 0x3FFF bytes, 0x0004 then 64 to 0x7FFF bytes, 0x0005 then 64 to
0xFFFF bytes. If 0x0008 to 0xFFFF then the number of bytes transmitted is fixed from 8 to 0xFFFF.
Register 3.F017 specifies the number of packets to burst. 0x0000 means stop generation, 0xFFFF
means continuously generate packets, 0x0001 to 0xFFFE means send a burst of 1 to 0xFFFE
packets.
Register 3.F018 specifies the gap between packets. Each increment in the value increases the idle
time by 4 bytes. 3.F018.14:0 specifies the upper limit of the gap. If 3.F018.15 is 0, then the lower
limit for IPG is also specified by 3.F018.14:0. Otherwise a random gap between 1 × 4 bytes to
3.F018.14:0 × 4 bytes will be used. For the purposes of counting IPG all lanes must be idle for it to
be counted as an IPG; that is, if the terminate symbol is in the XGMII word, then it does not count
towards the IPG.
Register 3.F012 and 3.F013 specifies the initial value of the payload or the fixed value of the
payload. The 4 bytes in this register corresponds to the first 4 bytes of the frame. Register
3.F011.7:4 specifies the behavior of the payload.
When 3.F011.7:4 = 000x, then registers 3.F012 and 3.F013 are used as the payload repeatedly.
When 3.F011.7:4 = 0010, then registers 3.F012 and 3.F013 are used as the payload repeatedly but
every other XGMII word should be inverted. That is, a payload of 034EA675 will result in a sequence
of 034EA675, FCB1598A, 034EA675, FCB1598A, ….
When 3.F011.7:4 = 0011, then registers 3.F012 and 3.F013 are used as the payload repeatedly but
inverted every second XGMII word. That is, a payload of 034EA675 will result in a sequence of
034EA675, 034EA675, FCB1598A, FCB1598A, 034EA675, 034EA675, FCB1598A, FCB1598A, ….
When 3.F011.7:4 = 0100, then registers 3.F012 and 3.F013 are used as the initial value and each
byte subsequently bitwise left shifted. That is, a payload of 034EA675 will result in a sequence of
034EA675, 069C4DEA, 0C399AD5, 187235AB, ….
When 3.F011.7:4 = 0101, then registers 3.F012 and 3.F013 are used as the initial value and each
byte subsequently bitwise right shifted.
When 3.F011.7:4 = 0110, then registers 3.F012 and 3.F013 are used as the initial value and the 32
bits subsequently bitwise left shifted. That is, a payload of C34EA675 will result in a sequence of
C34EA675, 869D4CEB, 0D3A99D7, 1A7533AE, ….
When 3.F011.7:4 = 0111, then registers 3.F012 and 3.F013 are used as the initial value and the 32
bits subsequently bitwise right shifted.
When 3.F011.7:4 = 1000, then registers 3.F012 and 3.F013 are used as the initial value and
subsequently bytewise incremented. That is, a payload of FFFE0055 will result in a sequence of
FFFE0055, 00FF0156, 01000257, 02010358, ….

When 3.F011.7:4 = 1001, then registers 3.F012 and 3.F013 are used as the initial value and
subsequently bytewise decremented.
When 3.F011.7:4 = 1010, then registers 3.F012 and 3.F013 are ignored and a pseudo random
payload is generated. All 4 bytes are the same value for each cycle.
When 3.F011.7:4 = 1011, then registers 3.F012 and 3.F013 are ignored and a pseudo random
payload is generated. All 4 bytes are randomly generated for each cycle.
At the start of each packet registers 3.F012 and 3.F013 should be used to reset the initial values to
ensure that the pattern in the packet is the same when repeated over and over many times. The only
time that the pattern in the packet will be different is when pseudo-random generation is selected.
For each packet generated the 48-bit counter in 3.F01B, 3.F01C, and 3.F01D is incremented by 1.
For each byte generated the 48-bit counter in 3.F01E, 3.F01F, and 3.F020 is incremented by 1.
Preamble bytes are not counted but CRC bytes are counted.
Register 3.F011.3 controls whether the CRC is generated or not.
4.6.2
Checker
The CRC checker is enabled by setting Register 3.F010.0 to 1.
If Register 3.F010.2 = 0, then the checker will wait until the start of frame delimiter (SFD) is detected
to detect the frame boundary.
If Register 3.F010.2 = 1, then the checker will assume the first 8 bytes of the packet is the preamble
and the frame starts at the ninth byte of the packet.
There are 3 sets of 48-bit counters for the checker.
Registers 3.F021, 3.F022, 3.F023 is the receive packet counter.
Register 3.F027, 3.F028, and 3.F029 is the receive packet error counter.
Register 3.F024, 3.F025, and 3.F026 is the receive byte counter.
The receive packet counter counts the number of packets received regardless of whether there is a
CRC error. The receive packet error counter increments once per packet with a CRC error. The byte
counter counts the number of bytes in the frame including the CRC. The preamble bytes are not
counted.
4.7
PRBS and Pattern Generators
The device supports various IEEE defined and proprietary PRBS generators and checkers, and
transmit waveform pattern generators. Only 1 generator/checker may be enabled at a time per lane.
Unpredictable results may occur if multiple generators are enabled simultaneously.
4.7.1
General PRBS Generators and Checkers
Each lane has its own general PRBS generator and checker. Port 0 registers controls lane 0, port 1
controls lane 1, port 2 controls lane 2, and port 3 controls lane 3.
Register 3.F030 controls the generator and checker. Setting register 3.F030.5 to 1 enables the
generator, and setting register 3.F030.4 to 1 enables the checker. If either of these bits is set to 1,
the general PRBS generator and checker overrides the PCS specific generators and checkers.
Register 3.F030.3:0 controls the pattern that is generated and checked. There is no checker for the
high frequency, low frequency, mixed frequency, and square wave patterns as there are waveforms
to check the transmitter performance.

All counters are 48 bits long. If register 3.F030.13 is set to 1 then the counters will clear on read. If
register 3.F030.13 is set to 0 then the counters will keep counting until register 3.F030.6 is set to 1 to
clear the contents. If register 3.F030.7 is set to 0, then the PRBS counters will not start to count until
the checker first locks onto the incoming PRBS data. If register 3.F030.7 is set to 1 then the PRBS
checker will start counting errors without first locking to the incoming PRBS data. Register 3.F030.8
indicates whether the PRBS checker has locked.
All 48-bit counters are formed by 3 16-bit registers. The lowest addressed register is the least
significant 16 bits and the highest addressed register is the most significant 16 bits of the counter.
When the least significant register is read, the 2 upper registers are updated and frozen so that the 3
register read is atomic. Note that it is not necessary to read the upper registers. However upon
subsequent reads of the least significant register, the values of the upper registers from the previous
reads are lost. In order to get the correct upper register value the least significant register must be
read first.
Register 3.F031, 3.F032, and 3.F033 is the transmit bit counter. Register 3.F034, 3.F035, and
3.F036 is the receive bit counter. Register 3.F037, 3.F038, and 3.F039 is the receive bit error
counter.
4.7.2
10GBASE-R Specific Generators and Checkers
Registers 3.002A.4 and 3.002A.5 when set to 1 enables the PRBS31 generator and checker
respectively. Register 3.002A.3 and 3.002A.2 when set to 1 enables the transmit and receive test
patterns respectively. Register 3.002A.1 selects the test pattern. The error counter is in register
3.002B.15:0 and clears on read.
4.8
Interrupt
The Line PCS supports several interrupts. The interrupt enable, interrupt status, and real time status
are shown in Table 50.
The INTn interrupt pin will be active if any of the events enabled in the interrupt enable register
occurs. If an interrupt event corresponding to a disabled interrupt enable bit occurs, the
corresponding interrupt status bit will be set even though the event does not activate the INTn pin.
The interrupts are cleared after a read to the interrupt status register.

Host-side Description
This section includes information on the following topics:
Section 5.1, Host Electrical Interface
Section 5.2, PCS
Section 5.3, Loopback
Section 5.4, Synchronizing FIFO
Section 5.5, Power Management
Section 5.6, Traffic Generation and Checking
Section 5.7, PRBS and Pattern Generators
Section 5.8, Interrupt
The host-side interface is comprised of 8 differential input lanes MIP[7:0]/MIN[7:0] and 8 differential
output lanes MOP[7:0]/MON[7:0]. They are designed to operate over short backplanes to the host
device. In this document, each set of input / output lanes is referred to as lane M0, M1, M2, M3, M4,
M5, M6, and M7.
These lanes can be arranged to form 4-ports of 1000BASE-X, 10GBASE-R, and RXAUI, and 2-ports
of XAUI.
5.1
Host Electrical Interface
The input and output buffers of the SERDES interface are internally terminated by 50Ω impedance
(100Ω differential). No external terminations are required.
The SERDES transmitter uses a 3 tap (1 pre-tap and 1 post-tap) FIR filter that is implemented for the
purpose of channel equalization. The FIR tap can be manually adjusted to optimize the transmit eye
over a particular channel.
The receiver performs clock and data recovery and de-serializes the data.
5.2
PCS
Each port supports a multiple number of different PCS. Section 3.1.2, PCS Operational Mode and
Lane Attachment, on page 42 describes how to configure each port for the various PCS. This
section focuses on the PCS itself.
5.2.1
10GBASE-R
The 10GBASE-R PCS is available on all ports. It is enabled by setting register 31.F002.6:0 to 0x71.
If register 31.F402.9 is set to 1, then lanes M0 through M3 are used by port 0 through 3 respectively.
If register 31.F402.9 is set to 0, then lanes M0, M2, M4, M6 are used by port 0 through 3
respectively.
In all other respects the 10GBASE-R functionality is identical to Section 4.2.1, 10GBASE-R,
on page 84 except the DEVAD is 4 instead of 3.
5.2.2
XAUI
The XAUI PCS is available only on ports 0 and 2. It is enabled by setting register 31.F002.6:0 to
0x73.

Normally lanes M0 to M3 are used by port 0 and correspond to lanes 0 to 3, and lanes M4 to M7 are
used by port 2 and corresponds to lanes 4 to 7. However, if register 4.9000.7 is set to 1, then the
lane order will be reversed with lanes M3 to M0 used by port 0 and corresponding to lanes 0 to 3,
and lanes M7 to M4 are by port 2 and corresponding to lanes 4 to 7. The reverse lane order
configuration only applies to the PCS. Access for all PMA registers is not lane reversed.
The XAUI PCS operates according to Clause 48 of the IEEE 802.3ae specification. The PCS uses a
8/10-bit coding across 4 lanes for DC line balancing. For details, see the IEEE 802.3 specification.

5.2.3
1000BASE-X
The 1000BASE-X PCS is available on all ports. There are several modes of 1000BASE-X.
It is enabled by setting register 31.F002.6:0 to 1 of the following values.
0x7A = 1000BASE-X, 1000BASE-X Auto-Negotiation off
0x7B = 1000BASE-X, 1000BASE-X Auto-Negotiation on

0x7E = SGMII (media), SGMII Auto-Negotiation off
0x7F = SGMII (media), SGMII Auto-Negotiation on
If register 31.F402.8 is set to 1, then lanes M0 through M3 are used by port 0 through 3 respectively.
If register 31.F402.8 is set to 0, then lanes M0, M2, M4, M6 are used by port 0 through 3
respectively.
In all other respects the 1000BASE-X functionality is identical to Section 4.2.2, 1000BASE-X,
on page 85 except the DEVAD is 4 instead of 3.

Loopback
The host-side SERDES supports 2 loopback paths.
If register 4.F003.12 = 1 then data from the host will loopback to the host as shown in Figure 27.

5.4
Synchronizing FIFO
Each port has a transmit synchronizing FIFOs to reconcile frequency differences between the
internal bus clocks and the clock used to transmit data onto the host interface. The depth of the
FIFO can be programmed by setting register 4.F00C.15:14.
The FIFO depths can be increased in length to support longer frames. The device has settings for
maximum frame sizes of the following:
10 Kb, 20 Kb, 40 Kb, and 80 Kb with up to ±100 ppm clock jitter in 10 Gbps operation
and
10 Kb, 15 Kb, 20 Kb, and 25 Kb with up to ±100 ppm clock jitter in 1 Gbps operation
The deeper the FIFO depth is, the higher the latency will be.
The FIFO overflow/underflow status is reported in register 4.F00B.1:0.
5.5
Power Management
The 88X2222 device will automatically power down unused circuits. The host side can be forced into
a power down state by setting 4.0000.11, 4.1000.11, 4.2000.11, or 4.3000.11 to 1. Register
31.0xF003.6 can also be used to power down the host-side port. These power down registers are
physically the same bit even though they reside in different locations. Since 31.0xF003.6 is
physically a separate register bit, setting this bit will not be reflected into PCS power down bits
previously mentioned, but will override them.
To soft reset only the host side, set registers 4.0000.15, 4.1000.15, 4.2000.15, or 4.3000.15.
Register 31.F003.7 can also be used to soft reset the host side. These software reset registers are
physically the same bit even though they reside in different locations.
5.6
Traffic Generation and Checking
This section describes the generator and checker functions. All counters are 48 bits long. If register
4.F010.14 is set to 1, the counters clear on read. If register 4.F010.14 is set to 0, then the counters
will keep counting unto 4.F010.6 is set to 1 to clear the contents.
5.6.1
Packet Generator
A packet generator enables the device to generate traffic onto the host without the need to receive
data from the media.
Register 4.F010.1 enables the internal packet generator.
Register 4.F016 specifies the number of bytes in the packet that is to be generated. This count
includes the frame bytes but does not include the 4 byte CRC (unless it is appended - register
4.F011.3 = 0), the terminate symbol, nor the 8 preamble bytes. The length depends upon the
register setting:
If the register is set to 0x0000, then the length will be randomly selected between
64 to 1518 bytes.
If the register is set to 0x0001, then the length will be randomly selected to be between
64 to 0x0FFF bytes.
If the register is set to 0x0002, then the length will be 64 to 0x1FFF bytes,
If the register is set to 0x0003, then the length will be 64 to 0x3FFF bytes,
If the register is set to 0x0004, then the length will be 64 to 0x7FFF bytes,
If the register is set to 0x0005, then the length will be 64 to 0xFFFF bytes.
If the register is set to 0x0008 to 0xFFFF, then the number of bytes transmitted is fixed from 8 to
0xFFFF.

Host-side Description
Traffic Generation and Checking
Register 4.F017 specifies the number of packets to burst. 0x0000 means stop generation, 0xFFFF
means continuously generate packets, 0x0001 to 0xFFFE means send a burst of 1 to 0xFFFE
packets.
Register 4.F018 specifies the gap between packets. Each increment in the value increases the idle
time by 4 bytes. 4.F018.14:0 specifies the upper limit of the gap. If 4.F018.15 is 0 then the lower limit
for IPG is also specified by 4.F018.14:0; otherwise, a random gap between 1 x 4 bytes to
4.F018.14:0 x 4 bytes will be used. For the purposes of counting IPG all lanes must be idle for it to
be counted as an IPG. In other words if the terminate symbol is in the XGMII word then it does not
count towards the IPG.
Register 4.F012 and 4.F013 specifies the initial value of the payload or the fixed value of the
payload. The 4 bytes in this register corresponds to the first 4 bytes of the frame. Register
4.F011.7:4 specifies the behavior of the payload.
When 4.F011.7:4 = 000x then registers 4.F012 and 4.F013 are used as the payload repeatedly.
When 4.F011.7:4 = 0010 then registers 4.F012 and 4.F013 are used as the payload repeatedly but
every other XGMII word should be inverted. That is, a payload of 034EA675 will result in a sequence
of 034EA675, FCB1598A, 034EA675, FCB1598A, ….
When 4.F011.7:4 = 0011 then registers 4.F012 and 4.F013 are used as the payload repeatedly but
inverted every second XGMII word. That is, a payload of 034EA675 will result in a sequence of
034EA675, 034EA675, FCB1598A, FCB1598A, 034EA675, 034EA675, FCB1598A, FCB1598A, ….
When 4.F011.7:4 = 0100 then registers 4.F012 and 4.F013 are used as the initial value and each
subsequent byte is shifted left bitwise. That is, a payload of 034EA675 will result in a sequence of
034EA675, 069C4DEA, 0C399AD5, 187235AB, ….
When 4.F011.7:4 = 0101 then registers 4.F012 and 4.F013 are used as the initial value and each
subsequent byte is shifted right bitwise.
When 4.F011.7:4 = 0110 then registers 4.F012 and 4.F013 are used as the initial value and the
subsequent 32 bits are shifted left bitwise. That is, a payload of C34EA675 will result in a sequence
of C34EA675, 869D4CEB, 0D3A99D7, 1A7533AE, ….
When 4.F011.7:4 = 0111 then registers 4.F012 and 4.F013 are used as the initial value and the
subsequent 32 bits are shifted right bitwise.
When 4.F011.7:4 = 1000, registers 4.F012 and 4.F013 are used as the initial value and
subsequently bytewise incremented. That is, a payload of FFFE0055 will result in a sequence of
FFFE0055, 00FF0156, 01000257, 02010358, ….
When 4.F011.7:4 = 1001, registers 4.F012 and 4.F013 are used as the initial value and
subsequently bytewise decremented.
When 4.F011.7:4 = 1000, registers 4.F012 and 4.F013 are ignored and a pseudo random payload is
generated. All 4 bytes are the same value for each cycle.
When 4.F011.7:4 = 1001 then registers 4.F012 and 4.F013 are ignored and a pseudo random
payload is generated. All 4 bytes are randomly generated for each cycle.
At the start of each packet registers 4.F012 and 4.F013 should be used to reset the initial values to
ensure that the pattern in the packet is the same when repeated many times. The only time that the
pattern in the packet will be different is when pseudo random generation is selected.
The following 48-bit counters are incremented by 1:
For each packet generated, 4.F01B, 4.F01C, and 4.F01D
For each byte generated, 4.F01E, 4.F01F, and 4.F020
Preamble bytes are not counted but CRC bytes are counted.
Register 4.F011.3 controls whether the CRC is generated or not.

5.6.2
Checker
The CRC checker is enabled by setting register 4.F010.0 to 1.
If register 4.F010.2 = 0, the checker will wait until the SFD is detected to detect the frame boundary.
If register 4.F010.2 = 1, the checker will assume the first 8 bytes of the packet is the preamble and
the frame starts at the ninth byte of the packet.
There are 3 sets of 48-bit counters for the checker:
Receive packet counter
• Registers 4.F021, 4.F022, 4.F023
• Counts the number of packets received regardless of whether there is a CRC error
Receive packet error counter
• Registers 4.F027, 4.F028, and 4.F029
• Increments once per packet with a CRC error
Receive byte counter
• Registers 4.F024, 4.F025, and 4.F026
• Counts the number of bytes in the frame including the CRC (note that preamble bytes are not
counted)
5.7
PRBS and Pattern Generators
The device supports various IEEE defined and proprietary PRBS generators and checkers, and
transmit waveform pattern generators. Only 1 generator/checker per lane may be enabled
simultaneously.
If multiple generators are enabled simultaneously, unpredictable results may occur.
Caution
5.7.1
General PRBS Generators and Checkers
Each lane has its own general PRBS generator and checker:
Port 0 registers control lanes 0 and 4
Port 1 registers control lanes 1 and 5
Port 2 registers control lanes 2 and 6
Port 3 registers control lanes 3 and 7
For lanes 0 to 3, the functionality is identical to Section 4.7.1, General PRBS Generators and
Checkers, on page 90 except the DEVAD is 4 instead of 3.
For lanes 4 to 7, the function of registers 4.F040 to 4.F049 is identical to registers 4.F030 to 4.F039
except the registers control a different lane.

Register 4.9010.2:0 can select any of the 5 jitter patterns specified by IEEE 802.3.
000 = Jitter 48A.1 (high freq)
001 = Jitter 48A.2 (low freq)
010 = Jitter 48A.3 (mix freq)
100 = Jitter 48A.4 (CRPAT)
101 = Jitter 48A.5 (CJPAT)
The transmit jitter pattern is enabled by setting 4.9010.4 to 1.
The 48A.1, 48A.2, and 48A.3 transmit patterns can also be enabled by setting register 3.1019.2 to 1
and selecting the pattern via register 3.1019.1:0.
There is a checker to check the CRPAT and CJPAT patterns. This is enabled by setting 4.9010.5
to 1.
Formation and incrementation of 32-bit counters is as follows:
Register 4.9011 and 4.9012
• Form 32-bit counter
• Increment once for every CRPAT or CJPAT packet transmitted
Register 4.9013 and 4.9014
• Form 32-bit counter
• Increment once for every CRPAT or CJPAT packet received
Register 4.9015 and 4.9016
• Form 32-bit counter
• Increment once for every CRPAT or CJPAT packet received with error
The lower addressed register is the least significant 16 bits and the higher addressed register is the
most significant 16 bits of the counter. When the least significant register is read, the upper register
is updated and frozen so that the two register read is atomic. The counters can be cleared only by
setting register 4.9010.7 to 1.
5.8
Interrupt
The Host PCS supports several interrupts. Table 51 shows the interrupt enable, interrupt status, and
real time status.
The INTn interrupt pin will be active if any of the events enabled in the interrupt enable register
occurs. If an interrupt event corresponding to a disabled interrupt enable bit occurs, the
corresponding interrupt status bit will be set even though the event does not activate the INTn pin.
The interrupts are cleared after a read to the interrupt status register.

Register 1.8002.10:8 is the status in response to setting to
writing register 1.8001.
Register 1.8002.10:8 will remain at 010 until the command
is completed. Once the command is completed the status
001, 011, 100, 101, or 111 will remain until register 1.8002
is read. The register will clear on read.
If a new command is issued by writing register 1.8001
without reading register 1.8002 for a previous command,
the status of the previous command will be lost.
If a command initiated by writing register 1.8001 is still in
progress and a second command is issued, the status
register 1.8002.10:8 will reflect the first command.
The second command is ignored but register 1.8002.10:8
will not be set to 111.
Command Done - No Error is set when the TWSI slave
properly responds with ACK.
In the case of a write command with automatic read back
a Command Done - No Error status will be returned even if
the read back data does not match the written data or if
the TWSI slave does not respond with ACK during the
read back.
Register 1.8002.7:0 is valid only when register
1.8002.10:8 is set to 001.

Register Description
SFI Registers
6.3.5
SFI SERDES Registers
By default LDSP tries to automatically train the link partner for the best transmitter settings. The
transmitter comes up with default settings which can be read back from registers in Table 201 to
Table 208. If manual forcing of transmitter amplitude/pre/post emphasis is desired, it can be
achieved by writing to the same registers. Here register address 1E.B116.15 should be read as
0x1E.0xB116 and so on. The registers in this section apply to ports 0 and 2.

XFI SERDES Registers
The transmitter comes up with default settings which can be read back from registers in Table 327 to
Table 334. If manual forcing of transmitter amplitude/pre/post emphasis is desired, it can be
achieved by writing to the same registers. Here register address 1E.80E6 should be read as
0x1E.0x80E6 and so on.

Current Consumption
7.4
Current Consumption
Current consumption numbers are estimates at this time and are subject to change.
Warning
The current consumption is broken down by each power supply. The total current consumption for
each power supply is calculated by summing the various components in the tables below. The total
chip power consumption is calculated as follows:
3
Isupply_Total = Isupply_Base +
3
Isupply_PCS(port N) +
N–0
Isupply_MS(port N)
N–0
Isupply_PCS = Current consumption for the PCS selected, 0 mA if the port is turned off.
Isupply_DSP = Incremental current consumption when the Electronic Dispersion Compensation DSP
Engine is enabled, otherwise 0 mA.
Supply is one of AVDD15, AVDD11, AVDD10, and DVDD.
The current consumption numbers for Isupply_PCS and Isupply_MS are per port.
The current consumption numbers for Isupply_DSP is per active lane on the line side.

XFI[3:0]_OUT 1 GbE Specifications
All voltage and jitter specifications at 1.25G are identical to the specifications at 10.3125G. Jitter and
mask parameters scale with data rate (same UI values).
7.6.4
XFI Receiver (XFI[3:0]_IN) Input Specifications
The specifications shown in Table 351 and Table 352 are at 10.3125G at the input of the chip
measured with a minimal loss channel from a test equipment of 2 × 50 impedance through AC
coupling.
Note
XFI receiver specifications are generally based on datacom applications for FC-PI-3,
point D. Point D sinusoidal jitter tolerance specifications account for the peaking
impairments of a CDR in an XFP module. However, the 88X2222 device’s receiver is
located at the same point in a system where FC-PI-3 defines a module to be, which is
point B. Since there is no CDR in this path, the sinusoidal jitter tolerance requirements
for point B are used.

1. Target WDP is calibrated with a reference receiver with 14 T/2 spaced FFE taps and 5 T spaced DFE taps.
2. Target RN rms values are given by the following equation: RN=m×(WDP-WDPi)+b, where WDP is the actual value of the
tester, and WDPi values are based on wave shapes expected at TP3.
3. The filter bandwidth in the TP3 to electrical adapter in SFF-8431 figure 52 is set to produce 5.4 dBo for WDP for the
split-symmetrical TP3 stressor. The same filter is to be used for high WDP pre-cursor LRM stressors – their approximate
target WDP values are given only for guidance. WDP is to measured for each stressor, and target RN is determined by the
relevant equation in note 2.
4. The filter bandwidth in TP3 to electrical adaptor in SFF-8431 Figure 52 is set to 7.5 GHz for all three LRM low WDP
conditions and for LR condition. The approximate target WDP values are given for guidance. WDP is to measured for each
stressor, and target RN is determined by relevant equation in note 2.
For LR, the SFP+ linear host shall operate with sinusoidal jitter given by Figure 12 in SFF-8431,
while the stress conditions given in Table 359 are applied. For LRM, the host shall operate with
sinusoidal jitter as defined in IEEE802.3 clause 68, with the other stressors and noises in SFF-8431,
Figure 52 turned off, including those in the TP3 tester.
