www.maximintegrated.com
15) Press the Read All button to read all registers on the
MAX9271 and MAX9272.
Detailed Description of Software
The main window of the evaluation software (Figure 1)
shows a block diagram representing the MAX9271/
MAX9272 system. The left column shows MAX9271
input data sources and the right column shows MAX9272
output data sinks.
The Change Configuration button brings up the
Software Connect window (Figure 7), allowing the software GUI to select which side of the link the USB cable
should be plugged into and the Jumper Setting window
(Figure 8) to help in configuring the boards. Controlling
from the MAX9272 side requires changing some jumper
settings, as described in this window. If the MAX9271
and MAX9272 device addresses have been previously
changed from their factory power-on-reset (POR) values,
the new addresses must be specified in the Software
Connect window to allow register access.
The Baud Rate drop-down list sets the communications
baud rate. The USB link uses the same baud rate as the
MAX9271/MAX9272. Note that the baud rate should only
be changed one step at a time.
The Read All button reads all MAX9271 and MAX9272
device registers. The Reset to Default Values button
restores the recommended factory settings and the Write
All button writes all MAX9271 and MAX9272 device
registers with the values shown in the GUI.
The MAX9271 tab sheet (Figure 2) provides direct
access to all MAX9271 registers and the MAX9272 tab
sheet (Figure 3) provides direct access to all MAX9272
registers. Each register has its own Read and Write
button. The small circle next to the Read button turns
yellow to indicate an attempting read or write, red to
indicate a failed read or write, or green to indicate a
successful read or write operation.
The MAX7324 tab sheet (Figure 4) controls the I2C I/O
expander on the remote side of the link. When the USB
is plugged into the MAX9271 coax EV kit, the MAX7324
tab sheet controls the MAX7324 (U15) on the MAX9272
coax EV kit. Note that the MAX7324 actually has two
device addresses, but for simplicity, the software GUI only
displays the device address associated with the MAX7324
outputs. For details, refer to MAX7324 IC data sheet.
Maxim Integrated │ 4
MAX9272 Coax Evaluation Kit
The PRBS Test tab sheet (Figure 5) uses the MAX9271
and MAX9272 registers to perform a pseudorandom
bit sequence (PRBS) error-rate test. Select the test
duration (maximum 32767s = 9.1hrs) and press Start.
The software GUI configures the MAX9271 and MAX9272
to begin the PRBS test, counts down the specified delay
time, and then reports the final value of the MAX9272
PRBSERR register.
The Interface History and Low Level Access tab sheet
(Figure 6) shows the recent low-level communications
activity between the software GUI and the MAX9271/
MAX9272 devices. The Register Access group provides
arbitrary device read/write control, supporting additional
user-supplied devices besides the on-board MAX9271,
Evaluates: MAX9271/MAX9272
with FAKRA Cable
MAX9272, and MAX7324. The Device Address,
Register, and Data drop-down lists specify the device
address and the register within the device, as well as
one optional byte of data to be written. Pressing Write
Register writes 1 byte of data to the specified device
register. Pressing Read Register reads the specified
device register and reports the result into the Interface
History window. Devices that are not register-based
(such as the MAX7324) are supported by Send Data (no
register) and Receive Data (no register). User-supplied
devices requiring other interface protocols must use Raw
TX byte codes to communicate. Note that in bypass
mode, raw data is passed to the user-supplied slave
device directly without modification.

MAX9272 Coax Evaluation Kit
Detailed Description of Hardware
The MAX9272 coax EV kit provides a proven layout
for the MAX9272 GMSL deserializer. On-board level
translators and easy-to-use USB-PC connection are
included on the EV kit.
The MAX9272 coax EV kit board layout is divided into four
principal sections:
● Power-supply circuitry. On-board LDO regulator U2
powers the AVDD, DVDD, and IOVDD supplies from
VIN.
● The MAX9272 and its support components.
● Microcontrollers (U10–U14).
● I2C slave device (U15).
The microcontroller and I2C slave device sections are
identical on the MAX9271, MAX9272, and MAX9273 EV
kits.
Microcontroller-Supplied I2C Interface
The microcontroller-supplied I2C interface (through U12
and U14) is intended to operate while both serializer and
deserialzer boards are powered on and locked. If the
microcontroller-supplied I2C interface is to be used in any
other case, one of the following should be done:
● Use an IOVDD of 2.2V or greater with the I2C
interface
● Use a 100kbps I2C data rate
User-Supplied Interface
To use the MAX9272 coax EV kit with a user-supplied
interface, first cut the PCB traces at jumpers JU141 and
JU142. Next, apply your own TX/SCL signal at the U1
side of JU141 and RX/SDA at the U1 side of JU142. Refer
to the MAX9271 and MAX9272 IC data sheets for details
about UART protocol for base mode, write data format,
read data format, selecting base mode or bypass mode,
and selecting a UART or I2C slave device.
User-Supplied Power Supply
The MAX9271 and MAX9272 coax EV kits are powered
completely from the USB port by default. Jumper
JU_USB+5V connects the 5V USB supply to the VIN
power supply.
To provide different power supplies to AVDD, DVDD, and
IOVDD, remove the shunts from jumpers JU21–JU23 and
apply external user-supplied power at the AVDD, DVDD,
and IOVDD oval PCB pads, respectively.

Detailed Description of Firmware
The DS89C450 microcontroller (U12) runs custom
firmware that ensures that no breaks occur within
register read/write commands. The firmware records 9-bit
even-parity data received from the USB interface while
RTS is set, and plays back the 9-bit data with 1.5 stop
bits timing when RTS is cleared. Data received from the
MAX9272 is immediately relayed to the USB.
The firmware also supports a small set of commands,
available when RTS is clear. Since all register read/
write requests are sent with RTS set, there is no
conflict between register data and firmware commands.
These firmware commands are issued automatically by
the MAX9271 coax EV kit software GUI. The following
information is provided for reference only:
● Firmware command “?” prints the firmware version
banner message and brief command list.
● Firmware command “B” changes the baud rate by
changing the internal TH1 baud-rate divisor. Refer to
the firmware help command “?” for details. Pressing
SW122 resets the USB baud rate to 921,600 baud.
The software GUI automatically sends the baud-rate
change command.
● Firmware command “T” supports waking up the
MAX9271 from the MAX9272 side of the link.
Command “T” performs a dummy read, followed by a
delay on the order of 1ms to 8ms, and finally writes a
register value. For example, send “T810504800483”
to read from device address 0x81 register 0x05, delay
4ms, then write to device address 0x80 register 0x04
data 0x83. This is the MAX9271 wake-up sequence
for the default device addresses.
● Firmware commands “R” and “W” read and write
device registers. The 8-bit device address, register
address, length, and data are sent in hexadecimal. On
success, the return code is “+” followed by the read
data. On failure, the return code is “-”.
● Some commands are used only during firmware
development. Firmware command “S” simulates a
dummy device using on-chip memory instead of
device registers, used during firmware development.
Firmware command “~” prints a diagnostic trace
dump used during firmware development. Firmware
commands “1” and “2” perform HDCP link
authentication check operations, used during firmware
development. In normal operation, these operations
not used for the MAX9272.
