Multi-pin signals such as LDP[0:3] have their physical package pin numbers listed in order corresponding to the signal names. 2. Stub series terminated logic type pins. 3. All SSI signals are multiplexed with eLBC signals. 4. Low voltage transistor-transistor logic (LVTTL) type pins. 5. DIU_LD[23:16] = RED[7:0] DIU_LD[15:8] = GREEN[7:0] DIU_LD[7:0] = BLUE[7:0] 6. The pins for the SSI interface on the device are multiplexed with certain eLBC signals, which have the ability to operate at a different voltage than the other standard I/O signals. If the device is configured such that the eLBC uses a different voltage than standard I/O and an SSI port on the device is used, then level shifters are required on the SSI signals to ensure they correctly interface to other devices on the board at the proper voltage. 7. This pin should be pulled to ground with a 100-Ω resistor. 8. This pin should be pulled to ground with a 200-Ω resistor. 9. These pins should be left floating. 10.This is a SerDes PLL/DLL digital test signal and is only for factory use. 11.This is a SerDes PLL/DLL analog test signal and is only for factory use. 12.This pin should be pulled down if the platform frequency is 400 MHz or below. 13.This pin should be pulled down if the core frequency is 800 MHz or below. 14.MSRCID[1:2], DIU_LD[5:6] and TRIG_OUT/READY should NOT be pulled down (or driven low) during reset.15. The pins in this section are reset configuration pins. Each pin has a weak internal pull-up P-FET which is enabled only when the processor is in the reset state. This pull-up is designed such that it can be overpowered by an external 4.7-kΩ pull-down resistor. However, if the signal is intended to be high after reset, and if there is any device on the net which might pull down the value of the net at reset, then a pullup or active driver is needed. 16.These pins should be left floating. 17.Must be tied low if unused. 18.This output is actively driven during reset rather than being tri-stated during reset. 19.MDIC[0] should be connected to ground with an 18-Ω resistor ± 1-Ω and MDIC[1] should be connected to GVDD with an 18-Ω resistor ± 1-Ω. These pins are used for automatic calibration of the DDR IOs. 20.This pin is a reset configuration pin and appears again in the Reset Configuration Signals section of this table. See the Reset Configuration Signals section of this table for config name and connection details. 21.Recommend a weak pull-up resistor (1–10 kΩ) be placed from this pin to its power supply. 22.This multiplexed pin has input status in one mode and output in another. 23.This pin is a multiplexed signal for different functional blocks and appears more than once in this table. 24.For systems which boot from local bus (GPCM)-controlled flash, a pullup on LGPL4 is required. 25.This pin is open drain signal. 26.These are test signals for factory use only and must be pulled up (100-Ω to 1- kΩ.) to OVDD for normal machine operation. 27.These JTAG pins have weak internal pull-up P-FETs that are always enabled. 28.These pins are connected to the power/ground planes internally and may be used by the core power supply to improve tracking and regulation.

The numbers are based on 100% utilization for each component. The components listed are not expected to have 100% usage simultaneously for all components. Actual numbers may vary based on activity. Note that the production parts should have a total maximum power value based on Table 5. The ‘Est.’ in the Est. Power column is to emphasize that these numbers are based on theoretical estimates. The device is tested to ensure that the sum of all four supplies does not exceed the power stated in Table 5. No specific supply should ever exceed its individual amount estimated in Table 6. 2.3.1 Frequency Derating To reduce power consumption, these devices support frequency derating if the reduced maximum processor core frequency and reduced maximum platform frequency requirements are observed. The reduced maximum processor core frequency, resulting maximum platform frequency and power consumption are provided in Table 7.

Caution: The platform to SYSCLK clock ratio and e600 core to platform clock ratio settings must be chosen such that the resulting SYSCLK, platform, and e600 (core) frequencies do not exceed their respective maximum or minimum operating frequencies. Refer to Section 3.1.2, “Platform/MPX to SYSCLK PLL Ratio” and Section 3.1.3, “e600 Core to MPX/Platform Clock PLL Ratio,” for ratio settings. 2. Rise and fall times for SYSCLK are measured at 0.4 and 2.7 V. 3. Timing is guaranteed by design and characterization. 4. This represents the short term jitter only and is guaranteed by design. 5. The SYSCLK driver’s closed loop jitter bandwidth should be 400 MHz, cfg_net2_div = 1. Therefore, when operating PCI Express in x8 link width, the MPX platform frequency must be 333-400 MHz with cfg_net2_div = 0 or greater than or equal to 527 MHz with cfg_net2_div = 1. For proper Serial RapidIO operation, the MPX clock frequency must be greater than: 2 × (0.80) × (Serial RapidIO interface frequency) × (Serial RapidIO link width) 64 MPC8610 Integrated Host Processor Hardware Specifications, Rev. 0 Freescale Semiconductor 25 Electrical Characteristics 2.4.5 Other Input Clocks For information on the input clocks of other functional blocks of the platform such as SerDes see the specific section of this document. 2.5 RESET Initialization Table 12.

This should be subtracted from the total timing budget. 2. The amount of skew that can be tolerated from MDQS to a corresponding MDQ signal is called tDISKEW.This can be determined by the following equation: tDISKEW = ±(T/4 – abs(tCISKEW)), where T is the clock period and abs(tCISKEW) is the absolute value of tCISKEW. 3. Maximum DDR1 frequency is 400 MHz. Minimum DDR2 frequency is 400 MHz. Figure 4 shows the DDR SDRAM input timing for the MDQS to MDQ skew measurement (tDISKEW).

The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. Output hold time can be read as DDR timing (DD) from the rising or falling edge of the reference clock (KH or KL) until the output went invalid (AX or DX). For example, tDDKHAS symbolizes DDR timing (DD) for the time tMCK m emory clock reference (K) goes from the high (H) state until outputs (A) are setup (S) or output valid time. Also, tDDKLDX symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes low (L) until data outputs (D) are invalid (X) or data output hold time. 2. All MCK/MCK referenced measurements are made from the crossing of the two signals ±0.1 V. 3. ADDR/CMD includes all DDR SDRAM output signals except MCK/MCK, MCS, and MDQ/MECC/MDM/MDQS. 4. Note that tDDKHMH follows the symbol conventions described in note 1. For example, tDDKHMH describes the DDR timing (DD) from the rising edge of the MCK[n] clock (KH) until the MDQS signal is valid (MH). tDDKHMH can be modified through control of the DQSS override bits in the TIMING_CFG_2 register. This will typically be set to the same delay as the clock adjust in the CLK_CNTL register. The timing parameters listed in the table assume that these 2 parameters have been set to the same adjustment value. See the MPC8610 Integrated Host Processor Reference Manual, for a description and understanding of the timing modifications enabled by use of these bits. 5. Determined by maximum possible skew between a data strobe (MDQS) and any corresponding bit of data (MDQ), ECC (MECC), or data mask (MDM). The data strobe should be centered inside of the data eye at the pins of the microprocessor. 6. All outputs are referenced to the rising edge of MCK[n] at the pins of the microprocessor. Note that tDDKHMP follows the symbol conventions described in note 1. 7. Maximum DDR1 frequency is 400 MHz. Minimum DDR2 frequency is 400 MHz. 8. Per the JEDEC spec the DDR2 duty cycle at 400 and 533 MHz is the low and high cycle time values. NOTE For the ADDR/CMD setup and hold specifications in Table 22, it is assumed that the clock control register is set to adjust the memory clocks by 1/2 applied cycle.

Parameter Noise margin at the HIGH level for each connected device (including hysteresis) Symbol1 VNH Min 0.2 × OV DD Max — Unit V Note: 1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tI2DVKH symbolizes I2C timing (I2) with respect to the time data input signals (D) reach the valid state (V) relative to the tI2C clock reference (K) going to the high (H) state or setup time. Also, tI2SXKL symbolizes I2C timing (I2) for the time that the data with respect to the start condition (S) went invalid (X) relative to the tI2C clock reference (K) going to the low (L) state or hold time. Also, tI2PVKH symbolizes I2C timing (I2) for the time that the data with respect to the stop condition (P) reaching the valid state (V) relative to the tI2C clock reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall). 2. As a transmitter, the MPC8610 provides a delay time of at least 300 ns for the SDA signal (referred to the V IHmin of the SCL signal) to bridge the undefined region of the falling edge of SCL to avoid unintended generation of Start or Stop condition. When MPC8610 acts as the I2C bus master while transmitting, MPC8610 drives both SCL and SDA. As long as the load on SCL and SDA are balanced, MPC8610 would not cause unintended generation of Start or Stop condition. Therefore, the 300 ns SDA output delay time is not a concern. If, under some rare condition, the 300 ns SDA output delay time is required for MPC8610 as transmitter, the following setting is recommended for the FDR bit field of the I2CFDR register to ensure both the desired I2C SCL clock frequency and SDA output delay time are achieved, assuming that the desired I2C SCL clock frequency is 400 kHz and the digital filter sampling rate register (I2CDFSRR) is programmed with its default setting of 0x10 (decimal 16): I2C Source Clock Frequency 533 MHz 400 MHz 333 MHz 266 MHz FDR Bit Setting 0x0A 0x07 0x2A 0x05 Actual FDR Divider Selected 1536 1024 896 704 Actual I2C SCL Frequency Generated 347 kHz 391 kHz 371 kHz 378 kHz For the detail of I2C frequency calculation, refer to Freescale application note AN2919, Determining the I2C Frequency Divider Ratio for SCL. Note that the I2C source clock frequency is equal to the MPX clock frequency for MPC8610. 3. The maximum tI2DXKL has only to be met if the device does not stretch the LOW period (tI2CL) of the SCL signal. 4. CB = capacitance of one bus line in pF. 5. Guaranteed by design.

PCI Output AC Timing Measurement Condition 2.17 High-Speed Serial Interfaces (HSSI) The MPC8610 features two Serializer/Deserializer (SerDes) interfaces to be used for high-speed serial interconnect applications. The SerDes1 interface is dedicated for PCI Express (x1/x2/x4) data transfers. The SerDes2 interface is dedicated for PCI Express (x1/x2/x4/x8) data transfers. This section describes the common portion of SerDes DC electrical specifications, which is the DC requirement for SerDes reference clocks. The SerDes data lane’s transmitter and receiver reference circuits are also shown. 2.17.1 Signal Terms Definition The SerDes utilizes differential signaling to transfer data across the serial link. This section defines terms used in the description and specification of differential signals. Figure 29 shows how the signals are defined. For illustration purpose, only one SerDes lane is used for description. The figure shows waveform for either a transmitter output (SD n_TX and SDn_TX) or a receiver input (SDn_RX and SDn_RX). Each signal swings between A volts and B volts where A > B. Using this waveform, the definitions are as follows. To simplify illustration, the following definitions assume that the SerDes transmitter and receiver operate in a fully symmetrical differential signaling environment. 1. Single-ended swing The transmitter output signals and the receiver input signals SDn_TX, SD n_TX, SDn_RX, and SDn_RX each have a peak-to-peak swing of A – B volts. This is also referred as each signal wire’s single-ended swing. Differential output voltage, VOD (or differential output swing): The differential output voltage (or swing) of the transmitter, V OD, is defined as the difference of the two complimentary output voltages: VSDn_TX – VSDn_TX. The VOD value can be either positive or negative. 2. MPC8610 Integrated Host Processor Hardware Specifications, Rev. 0 54 Freescale Semiconductor Electrical Characteristics 3. Differential input voltage, VID (or differential input swing): The differential input voltage (or swing) of the receiver, VID, is defined as the difference of the two complimentary input voltages: V SDn_RX – VSDn_RX. The V ID value can be either positive or negative. Differential peak voltage, VDIFFp The peak value of the differential transmitter output signal or the differential receiver input signal is defined as differential peak voltage, VDIFFp = |A – B| volts. Differential peak-to-peak, VDIFFp-p Since the differential output signal of the transmitter and the differential input signal of the receiver each range from A – B to -(A – B) volts, the peak-to-peak value of the differential transmitter output signal or the differential receiver input signal is defined as differential peak-to-peak voltage, VDIFFp-p = 2 * V DIFFp = 2 * |(A – B)| volts, which is twice of differential swing in amplitude, or twice of the differential peak. For example, the output differential peak-peak voltage can also be calculated as VTX-DIFFp-p = 2 * |VOD|. Differential waveform The differential waveform is constructed by subtracting the inverting signal (SD n_TX, for example) from the noninverting signal (SDn_TX, for example) within a differential pair. There is only one signal trace curve in a differential waveform. The voltage represented in the differential waveform is not referenced to ground. Refer to Figure 38 as an example for differential waveform. Common mode voltage, Vcm The common mode voltage is equal to one half of the sum of the voltages between each conductor of a balanced interchange circuit and ground. In this example, for SerDes output, Vcm_out = (VSDn_TX + VSDn_TX)/2 = (A + B)/2, which is the arithmetic mean of the two complimentary output voltages within a differential pair. In a system, the common mode voltage may often differ from one component’s output to the other’s input. Sometimes, it may be even different between the receiver input and driver output circuits within the same component. It’s also referred as the DC offset in some occasion. SDn_TX or SDn_RX 4. 5. 6. 7. A Volts Vcm = (A + B) / 2 SDn_TX or SDn_RX B Volts Differential Swing, VID or VOD = A – B Differential Peak Voltage, VDIFFp = |A – B| Differential Peak-Peak Voltage, V DIFFpp = 2*VDIFFp (not shown) Figure 29. Differential Voltage Definitions for Transmitter or Receiver To illustrate these definitions using real values, consider the case of a CML (current mode logic) transmitter that has a common mode voltage of 2.25 V and each of its outputs, TD and TD, has a swing that goes between 2.5 and 2.0 V. Using these values, the peak-to-peak voltage swing of each signal (TD or TD) is 500 mV p-p, which is referred as the single-ended swing for each signal. In this example, since the differential signaling environment is fully symmetrical, the transmitter output’s differential swing (VOD) has the same amplitude as each signal’s single-ended swing. The differential output signal ranges between 500 mV and –500 mV, in other words, V OD is 500 mV in one phase and –500 mV in the other phase. The peak differential voltage (VDIFFp) is 500 mV. The peak-to-peak differential voltage (V DIFFp-p) is 1000 mV p-p.

The SerDes reference clocks inputs are SD n_REF_CLK and SDn_REF_CLK for PCI Express. The following sections describe the SerDes reference clock requirements and some application information. 2.17.2.1 • • SerDes Reference Clock Receiver Characteristics Figure 30 shows a receiver reference diagram of the SerDes reference clocks. The supply voltage requirements for X nVDD are specified in Table 2 and Table 3. SerDes reference clock receiver reference circuit structure — The SDn_REF_CLK and SD n_REF_CLK are internally AC-coupled differential inputs as shown in Figure 30. Each differential clock input (SDn_REF_CLK or SDn_REF_CLK) has a 50-Ω termination to SGND followed by on-chip AC-coupling. — The external reference clock driver must be able to drive this termination. — The SerDes reference clock input can be either differential or single-ended. Refer to the differential mode and single-ended mode description below for further detailed requirements. The maximum average current requirement that also determines the common mode voltage range — When the SerDes reference clock differential inputs are DC coupled externally with the clock driver chip, the maximum average current allowed for each input pin is 8 mA. In this case, the exact common mode input voltage is not critical as long as it is within the range allowed by the maximum average current of 8 mA (refer to the following bullet for more detail), since the input is AC-coupled on-chip. — This current limitation sets the maximum common mode input voltage to be less than 0.4 V (0.4 V/50 = 8 mA) while the minimum common mode input level is 0.1 V above SGND. For example, a clock with a 50/50 duty cycle can be produced by a clock driver with output driven by its current source from 0 to 16 mA (0–0.8 V), such that each phase of the differential input has a single-ended swing from 0 V to 800 mV with the common mode voltage at 400 mV. — If the device driving the SDn_REF_CLK and SDn_REF_CLK inputs cannot drive 50 Ω to SGND DC, or it exceeds the maximum input current limitations, then it must be AC-coupled off-chip. The input amplitude requirement — This requirement is described in detail in the following sections. • • 50 Ω SDn_REF_CLK Input Amp SDn_REF_CLK 50 Ω Figure 30. Receiver of SerDes Reference Clocks MPC8610 Integrated Host Processor Hardware Specifications, Rev. 0 56 Freescale Semiconductor Electrical Characteristics 2.17.2.2 DC Level Requirement for SerDes Reference Clocks The DC level requirement for the MPC8610 SerDes reference clock inputs is different depending on the signaling mode used to connect the clock driver chip and SerDes reference clock inputs as described below. • Differential mode — The input amplitude of the differential clock must be between 400 and 1600 mV differential peak-peak (or between 200 and 800 mV differential peak). In other words, each signal wire of the differential pair must have a single-ended swing less than 800 mV and greater than 200 mV. This requirement is the same for both external DCor AC-coupled connection. — For external DC-coupled connection, as described in Section 2.17.2.1, “SerDes Reference Clock Receiver Characteristics,” the maximum average current requirements sets the requirement for average voltage (common mode voltage) to be between 100 and 400 mV. Figure 31 shows the SerDes reference clock input requirement for DC-coupled connection scheme. — For external AC-coupled connection, there is no common mode voltage requirement for the clock driver. Since the external AC-coupling capacitor blocks the DC level, the clock driver and the SerDes reference clock receiver operate in different command mode voltages. The SerDes reference clock receiver in this connection scheme has its common mode voltage set to SGND. Each signal wire of the differential inputs is allowed to swing below and above the command mode voltage (SGND). Figure 32 shows the SerDes reference clock input requirement for AC-coupled connection scheme. Single-ended mode — The reference clock can also be single-ended. The SDn_REF_CLK input amplitude (single-ended swing) must be between 400 and 800 mV peak-peak (from Vmin to Vmax) with SDn_REF_CLK either left unconnected or tied to ground. — The SDn_REF_CLK input average voltage must be between 200 and 400 mV. Figure 33 shows the SerDes reference clock input requirement for single-ended signaling mode. — To meet the input amplitude requirement, the reference clock inputs might need to be DC- or AC-coupled externally. For the best noise performance, the reference of the clock could be DC- or AC-coupled into the unused phase (SDn_REF_CLK) through the same source impedance as the clock input (SDn_REF_CLK) in use. 200 mV < Input Amplitude or Differential Peak < 800 mV SDn_REF_CLK Vmax < 800 mV 100 mV < Vcm < 400 mV • SDn_REF_CLK Vmin > 0 V Figure 31. Differential Reference Clock Input DC Requirements (External DC-Coupled) 200mV < Input Amplitude or Differential Peak < 800 mV SDn_REF_CLK Vmax < Vcm + 400 mV Vcm SDn_REF_CLK Vmin > Vcm – 400 mV Figure 32.

Single-Ended Reference Clock Input DC Requirements 2.17.2.3 • • Interfacing With Other Differential Signaling Levels • With on-chip termination to SGND, the differential reference clocks inputs are HCSL (high-speed current steering logic) compatible DC-coupled. Many other low voltage differential type outputs like LVDS (low voltage differential signaling) can be used but may need to be AC-coupled due to the limited common mode input range allowed (100 to 400 mV) for DC-coupled connection. LVPECL outputs can produce signal with too large amplitude and may need to be DC-biased at clock driver output first, then followed with series attenuation resistor to reduce the amplitude, in addition to AC-coupling. NOTE Figure 34 to Figure 37 are for conceptual reference only. Due to the fact that clock driver chip's internal structure, output impedance and termination requirements are different between various clock driver chip manufacturers, it is very possible that the clock circuit reference designs provided by clock driver chip vendor are different from what is shown below. They might also vary from one vendor to the other. Therefore, Freescale Semiconductor can neither provide the optimal clock driver reference circuits nor guarantee the correctness of the following clock driver connection reference circuits. The system designer is recommended to contact the selected clock driver chip vendor for the optimal reference circuits with the MPC8610 SerDes reference clock receiver requirement provided in this document. Figure 34 shows the SerDes reference clock connection reference circuits for HCSL type clock driver. It assumes that the DC levels of the clock driver chip is compatible with MPC8610 SerDes reference clock input’s DC requirement.

DC-Coupled Differential Connection with HCSL Clock Driver (Reference Only) Figure 35 shows the SerDes reference clock connection reference circuits for LVDS type clock driver. Since LVDS clock driver’s common mode voltage is higher than the MPC8610 SerDes reference clock input’s allowed range (100 to 400 mV), AC-coupled connection scheme must be used. It assumes the LVDS output driver features 50-Ω termination resistor. It also assumes that the LVDS transmitter establishes its own common mode level without relying on the receiver or other external component.

AC-Coupled Differential Connection with LVDS Clock Driver (Reference Only) Figure 36 shows the SerDes reference clock connection reference circuits for LVPECL type clock driver. Since LVPECL driver’s DC levels (both common mode voltages and output swing) are incompatible with MPC8610 SerDes reference clock input’s DC requirement, AC-coupling has to be used. Figure 36 assumes that the LVPECL clock driver’s output impedance is 50 Ω. R1 is used to DC-bias the LVPECL outputs prior to AC-coupling. Its value could be ranged from 140 to 240 Ω depending on clock driver vendor’s requirement. R2 is used together with the SerDes reference clock receiver’s 50-Ω termination resistor to attenuate the LVPECL output’s differential peak level such that it meets the MPC8610 SerDes reference clock’s differential input amplitude requirement (between 200 and 800 mV differential peak). For example, if the LVPECL output’s differential peak is 900 mV and the desired SerDes reference clock input amplitude is selected as 600 mV, the attenuation factor is 0.67, MPC8610 Integrated Host Processor Hardware Specifications, Rev. 0 Freescale Semiconductor 59 Electrical Characteristics which requires R2 = 25 Ω.

Single-Ended Connection (Reference Only) 2.17.2.4 AC Requirements for SerDes Reference Clocks The clock driver selected should provide a high quality reference clock with low phase noise and cycle-to-cycle jitter. Phase noise less than 100 kHz can be tracked by the PLL and data recovery loops and is less of a problem. Phase noise above 15 MHz is filtered by the PLL. The most problematic phase noise occurs in the 1–15 MHz range. The source impedance of the clock driver should be 50 Ω to match the transmission line and reduce reflections which are a source of noise to the system.
