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.

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. Only those parameters in Table 7 are affected; all other parameter specifications are unaffected. Table 7.

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.

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.

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 memory 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. 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.

Also, tLBKHOX symbolizes local bus timing (LB) for the tLBK clock reference (K) to go high (H), with respect to the output (O) going invalid (X) or output hold time. 2.

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. Guaranteed by design. Figure 15 provides the AC test load for the I2C.

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 (SDn_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, SDn_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. 2. 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. 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. 4. 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. 5. 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 MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 54 Freescale Semiconductor Electrical Characteristics 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|. 6. Differential waveform The differential waveform is constructed by subtracting the inverting signal (SDn_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. 7. 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. A Volts SDn_TX or SDn_RX Vcm = (A + B) / 2 B Volts SDn_TX or SDn_RX 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. 2.17.2 SerDes Reference Clocks The SerDes reference clock inputs are applied to an internal PLL whose output creates the clock used by the corresponding SerDes lanes. The SerDes reference clocks inputs are SDn_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 XnVDD are specified in Table 2 and Table 3. MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 55 Electrical Characteristics • • • SerDes reference clock receiver reference circuit structure — The SDn_REF_CLK and SDn_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 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. MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 56 Freescale Semiconductor Electrical Characteristics • — 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. Differential Reference Clock Input DC Requirements (External AC-Coupled) 400 mV < SDn_REF_CLK Input Amplitude < 800 mV SDn_REF_CLK 0V SDn_REF_CLK Figure 33. Single-Ended Reference Clock Input DC Requirements MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 57 Electrical Characteristics 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, which requires R2 = 25 Ω. Please consult clock driver chip manufacturer to verify whether this connection scheme is compatible with a particular clock driver chip.

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.

It is measured using a 200 mV window centered on the median cross point where SDn_REF_CLK rising meets SDn_REF_CLK falling. The median cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate calculations. The rise edge rate of SDn_REF_CLK should be compared to the fall edge rate of SDn_REF_CLK, the maximum allowed difference should not exceed 20% of the slowest edge rate. See Figure 39.

All outputs are measured from the midpoint voltage of the falling/rising edge of tTCLK to the midpoint of the signal in question. The output timings are measured at the pins. All output timings assume a purely resistive 50-Ω load (see Figure 15). Time-of-flight delays must be added for trace lengths, vias, and connectors in the system. 2. 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, tJTDVKH symbolizes JTAG device timing (JT) with respect to the time data input signals (D) reaching the valid state (V) relative to the tJTG clock reference (K) going to the high (H) state or setup time. Also, tJTDXKH symbolizes JTAG timing (JT) with respect to the time data input signals (D) went invalid (X) relative to the tJTG clock reference (K) going to the high (H) state. Note that, in general, the clock reference symbol representation is based on three letters representing the clock of a particular functional. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall). 3. TRST is an asynchronous level sensitive signal.

Note that the platform clock is identical to the internal MPX bus clock. This device includes six PLLs, as follows: 1. The platform PLL generates the platform clock from the externally supplied SYSCLK input. The frequency ratio between the platform and SYSCLK is selected using the platform PLL ratio configuration bits as described in Section 3.1.2, “Platform/MPX to SYSCLK PLL Ratio.” 2. The e600 core PLL generates the core clock from the platform clock. The frequency ratio between the e600 core clock and the platform clock is selected using the e600 PLL ratio configuration bits as described in Section 3.1.3, “e600 Core to MPX/Platform Clock PLL Ratio.” 3. The PCI PLL generates the clocking for the PCI bus 4. Each of the two SerDes blocks has a PLL.

Also note that the DDR data rate is the determining factor in selecting the platform frequency, since the platform frequency must equal the DDR data rate.

The AVDD level should always be equivalent to VDD, and preferably these voltages will be derived directly from VDD through a low frequency filter scheme such as the following. There are a number of ways to reliably provide power to the PLLs, but the recommended solution is to provide independent filter circuits per PLL power supply, one to each of the AVDD type pins. By providing independent filters to each PLL the opportunity to cause noise injection from one PLL to the other is reduced. This circuit is intended to filter noise in the PLLs resonant frequency range from a 500 kHz to 10 MHz range. It should be built with surface mount capacitors with minimum effective series inductance (ESL). Consistent with the recommendations of Dr. Howard Johnson in High Speed Digital Design: A Handbook of Black Magic (Prentice Hall, 1993), multiple small capacitors of equal value are recommended over a single large value capacitor. Each circuit should be placed as close as possible to the specific AVDD type pin being supplied to minimize noise coupled from nearby circuits. It should be possible to route directly from the capacitors to the AVDD type pin, which is on the periphery of 783 FC-PBGA the footprint, without the inductance of vias. Figure 48 shows the filter circuit for the platform PLL power supplies (AVDD_PLAT). 10 Ω VDD_PLAT AVDD_Plat 2.2 µF 2.2 µF Low ESL Surface Mount Capacitors GND Figure 48.

MPC8610 PLL Power Supply Filter Circuit (for Core) The SDnAVDD signals provide power for the analog portions of the SerDes PLLs. To ensure stability of the internal clock, the power supplied to the PLL is filtered using a circuit similar to the one shown in Figure 50. For maximum effectiveness, the filter circuit is placed as closely as possible to the SDnAV DD balls to ensure it filters out as much noise as possible. The ground connection should be near the SDnAV DD balls. The 0.003-µF capacitor is closest to the balls, followed by the two 2.2-µF capacitors, and finally the 1 ohm resistor to the board supply plane. The capacitors are connected from SDnAVDD to the ground plane. Use ceramic chip capacitors with the highest possible self-resonant frequency. All traces should be kept short, wide and direct. SVDD 1.0 Ω SDnAVDD 2.2 µF 1 2.2 µF 1 0.003 µF GND 1. An 0805 sized capacitor is recommended for system initial bring-up. Figure 50. SerDes PLL Power Supply Filter MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 76 Freescale Semiconductor Hardware Design Considerations Note the following: • • 3.3 SDnAVDD should be a filtered version of SVDD. Signals on the SerDes interface are fed from the SVDD power plane. Decoupling Recommendations Due to large address and data buses, and high operating frequencies, the device can generate transient power surges and high frequency noise in its power supply, especially while driving large capacitive loads. This noise must be prevented from reaching other components in the MPC8610 system, and the device itself requires a clean, tightly regulated source of power. Therefore, it is recommended that the system designer place at least one decoupling capacitor at each V DD, BVDD, OVDD, GVDD, VDD_Core, and VDD_PLAT pin of the device. These decoupling capacitors should receive their power from separate VDD, BVDD, OVDD, GVDD, VDD_Core, V DD_PLAT, and GND power planes in the PCB, utilizing short traces to minimize inductance. Capacitors may be placed directly under the device using a standard escape pattern. Others may surround the part. These capacitors should have a value of 0.01 or 0.1 µF. Only ceramic SMT (surface mount technology) capacitors should be used to minimize lead inductance, preferably 0402 or 0603 sizes. In addition, it is recommended that there be several bulk storage capacitors distributed around the PCB, feeding the VDD, BVDD, OVDD, GVDD, VDD_Core, and VDD_PLAT planes, to enable quick recharging of the smaller chip capacitors. These bulk capacitors should have a low ESR (equivalent series resistance) rating to ensure the quick response time necessary. They should also be connected to the power and ground planes through two vias to minimize inductance. Suggested bulk capacitors—100–330 µF (AVX TPS tantalum or Sanyo OSCON). 3.4 SerDes Block Power Supply Decoupling Recommendations The SerDes block requires a clean, tightly regulated source of power (SnVDD and XnVDD) to ensure low jitter on transmit and reliable recovery of data in the receiver. An appropriate decoupling scheme is outlined below. Only surface mount technology (SMT) capacitors should be used to minimize inductance. Connections from all capacitors to power and ground should be done with multiple vias to further reduce inductance. • • • 3.5 First, the board should have at least 10 x 10-nF SMT ceramic chip capacitors as close as possible to the supply balls of the device. Where the board has blind vias, these capacitors should be placed directly below the chip supply and ground connections. Where the board does not have blind vias, these capacitors should be placed in a ring around the device as close to the supply and ground connections as possible. Second, there should be a 1-µF ceramic chip capacitor on each side of the device. This should be done for all SerDes supplies. Third, between the device and any SerDes voltage regulator there should be a 10-µF, low equivalent series resistance (ESR) SMT tantalum chip capacitor and a 100-µF, low ESR SMT tantalum chip capacitor. This should be done for all SerDes supplies. Connection Recommendations To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal level. All unused active low inputs should be tied to VDD, BVDD, OVDD, GVDD, VDD_Core, V DD_PLAT, XnVDD, and SnVDD as required. All unused active high inputs should be connected to GND. All NC (no-connect) signals must remain unconnected. Power and ground connections must be made to all external V DD, BVDD, OVDD, GVDD, VDD_Core, VDD_PLAT, XnVDD, SnVDD, and GND pins of the device. Special cases: • Local Bus—If parity is not used, tie LDP[0:3] to ground via a 4.7-kΩ resistor, tie LPBSE to OVDD via a 4.7-kΩ resistor (pull-up resistor). For systems which boot from local bus (GPCM)-controlled Flash, a pull up on LGPL4 is required. MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 77 Hardware Design Considerations • 3.6 SerDes—Receiver lanes configured for PCI Express are allowed to be disconnected (as would occur when a PCI Express slot is connected but not populated). Directions for terminating the SerDes signals is discussed in Section 3.10, “Guidelines for High-Speed Interface Termination.” Pull-Up and Pull-Down Resistor Requirements The MPC8610 requires weak pull-up resistors (2–10 kΩ is recommended) on open drain type pins including I2C pins and PIC interrupt pins. Correct operation of the JTAG interface requires configuration of a group of system control pins as demonstrated in Figure 53. Care must be taken to ensure that these pins are maintained at a valid deasserted state under normal operating conditions as most have asynchronous behavior and spurious assertion will give unpredictable results. Refer to the PCI 2.2 specification for all pull-ups required for PCI. The following pins must not be pulled down during power-on reset: DIU_LD[5:6], MSRCID[1:2], HRESET_REQ, and TRIG_OUT/READY. The following are factory test pins and require strong pull up resistors (100 Ω – 1 kΩ) to OVDD: LSSD_MODE, TEST_MODE[0:3]. The following pins require weak pull-up resistors (2–10 kΩ) to their specific power supplies: LCS[0:4], LCS[5]/DMA_DREQ2, LCS[6]/DMA_DACK[2], LCS[7]/DMA_DDONE[2], IRQ_OUT, IIC1_SDA, IIC1_SCL, IIC2_SDA, IIC2_SCL, and CKSTP_OUT. The following pins should be pulled to ground with a 100-Ω resistor: SD1_IMP_CAL_TX, SD2_IMP_CAL_TX. The following pins should be pulled to ground with a 200-Ω resistor: SD1_IMP_CAL_RX, SD2_IMP_CAL_RX. When the platform frequency is 400 MHz, cfg_platform_freq must be pulled down at reset. Also, cfg_dram_type[0 or 1] must be valid at power-up even before HRESET assertion. For other pin pull-up or pull-down recommendations of signals, see Section 1, “Pin Assignments and Reset States.” 3.7 Output Buffer DC Impedance The MPC8610 drivers are characterized over process, voltage, and temperature. For all buses, the driver is a push-pull single-ended driver type (open drain for I2C). To measure Z0 for the single-ended drivers, an external resistor is connected from the chip pad to OVDD or GND. Then, the value of each resistor is varied until the pad voltage is OVDD/2 (see Figure 51). The output impedance is the average of two components, the resistances of the pull-up and pull-down devices. When data is held high, SW1 is closed (SW2 is open) and MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 78 Freescale Semiconductor Hardware Design Considerations RP is trimmed until the voltage at the pad equals OVDD/2. RP then becomes the resistance of the pull-up devices. RP and RN are designed to be close to each other in value. Then, Z0 = (RP + RN)/2. OVDD RN SW2 Pad Data SW1 RP OGND Figure 51. Driver Impedance Measurement Table 60 summarizes the signal impedance targets. The driver impedances are targeted at minimum VDD, nominal OVDD, 105°C. Table 60.

See Table 3, Tj = 105°C. 3.8 Configuration Pin Muxing The MPC8610 provides the user with power-on configuration options which can be set through the use of external pull-up or pull-down resistors of 4.7 kΩ on certain output pins (see customer visible configuration pins). These pins are generally used as output only pins in normal operation. While HRESET is asserted however, these pins are treated as inputs. The value presented on these pins while HRESET is asserted, is latched when HRESET deasserts, at which time the input receiver is disabled and the I/O circuit takes on its normal function. Most of these sampled configuration pins are equipped with an on-chip gated resistor of approximately 20 kΩ. This value should permit the 4.7-kΩ resistor to pull the configuration pin to a valid logic low level. The pull-up resistor is enabled only during HRESET (and for platform /system clocks after HRESET deassertion to ensure capture of the reset value). When the input receiver is disabled the pull-up is also, thus allowing functional operation of the pin as an output with minimal signal quality or delay disruption. The default value for all configuration bits treated this way has been encoded such that a high voltage level puts the device into the default state and external resistors are needed only when non-default settings are required by the user. Careful board layout with stubless connections to these pull-down resistors coupled with the large value of the pull-down resistor should minimize the disruption of signal quality or speed for output pins thus configured. The platform PLL ratio and e600 core PLL ratio configuration pins are not equipped with these default pull-up devices. MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 79 Hardware Design Considerations 3.9 JTAG Configuration Signals Correct operation of the JTAG interface requires configuration of a group of system control pins as demonstrated in Figure 53. Care must be taken to ensure that these pins are maintained at a valid deasserted state under normal operating conditions as most have asynchronous behavior and spurious assertion will give unpredictable results. Boundary-scan testing is enabled through the JTAG interface signals. The TRST signal is optional in the IEEE 1149.1 specification, but is provided on all processors that implement the Power Architecture technology. The device requires TRST to be asserted during reset conditions to ensure the JTAG boundary logic does not interfere with normal chip operation. While it is possible to force the TAP controller to the reset state using only the TCK and TMS signals, more reliable power-on reset performance will be obtained if the TRST signal is asserted during power-on reset. Because the JTAG interface is also used for accessing the common on-chip processor (COP) function, simply tying TRST to HRESET is not practical. The COP function of these processors allows a remote computer system (typically a PC with dedicated hardware and debugging software) to access and control the internal operations of the processor. The COP port connects primarily through the JTAG interface of the processor, with some additional status monitoring signals. The COP port requires the ability to independently assert HRESET or TRST in order to fully control the processor. If the target system has independent reset sources, such as voltage monitors, watchdog timers, power supply failures, or push-button switches, then the COP reset signals must be merged into these signals with logic. The arrangement shown in Figure 52 allows the COP port to independently assert HRESET or TRST, while ensuring that the target can drive HRESET as well. The COP interface has a standard header, shown in Figure 52, for connection to the target system, and is based on the 0.025" square-post, 0.100" centered header assembly (often called a Berg header). The connector typically has pin 14 removed as a connector key. The COP header adds many benefits such as breakpoints, watchpoints, register and memory examination/modification, and other standard debugger features. An inexpensive option can be to leave the COP header unpopulated until needed. There is no standardized way to number the COP header shown in Figure 53; consequently, many different pin numbers have been observed from emulator vendors. Some are numbered top-to-bottom then left-to-right, while others use left-to-right then top-to-bottom, while still others number the pins counter clockwise from pin 1 (as with an IC). Regardless of the numbering, the signal placement recommended in Figure 53 is common to all known emulators. 3.9.1 Termination of Unused Signals If the JTAG interface and COP header will not be used, Freescale recommends the following connections: • • • TRST should be tied to HRESET through a 0-kΩ isolation resistor so that it is asserted when the system reset signal (HRESET) is asserted, ensuring that the JTAG scan chain is initialized during the power-on reset flow. Freescale recommends that the COP header be designed into the system as shown in Figure 53. If this is not possible, the isolation resistor will allow future access to TRST in case a JTAG interface may need to be wired onto the system in future debug situations. Tie TCK to OVDD through a 10-kΩ resistor. This will prevent TCK from changing state and reading incorrect data into the device. No connection is required for TDI, TMS, or TDO.

JTAG Interface Connection MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 82 Freescale Semiconductor Hardware Design Considerations 3.10 Guidelines for High-Speed Interface Termination 3.10.1 SerDes Interface The high-speed SerDes interface can be disabled through the POR input cfg_io_ports[0:2] and through the DEVDISR register in software. If a SerDes port is disabled through the POR input the user can not enable it through the DEVDISR register in software. However, if a SerDes port is enabled through the POR input the user can disable it through the DEVDISR register in software. Disabling a SerDes port through software should be done on a temporary basis. Power is always required for the SerDes interface, even if the port is disabled through either mechanism. Table 61 describes the possible enabled/disabled scenarios for a SerDes port. The termination recommendations must be followed for each port. Table 61. SerDes Port Enabled/Disabled Configurations Disabled through POR input Enabled through DEVDISR Enabled through POR input SerDes port is disabled (and cannot SerDes port is enabled be enabled through DEVDISR) Partial termination may be required1 Complete termination required (Reference clock is required) (Reference clock not required Disabled through DEVDISR SerDes port is disabled (through POR input) Complete termination required (Reference clock not required) SerDes port is disabled after software disables port Same termination requirements as when the port is enabled through POR input2 (Reference clock is required) 1 Partial termination when a SerDes port is enabled through both POR input and DEVDISR is determined by the SerDes port mode. If port 1 is in x4 PCI Express mode, no termination is required because all pins are being used. If port 1 is in x1/x2 PCI Express mode, termination is required on the unused pins. If port 2 is in x8 PCI Express mode, no termination is required because all pins are being used. If port 1 is in x1/x2/x4 PCI Express mode, termination is required on the unused pins. 2 If a SerDes port is enabled through the POR input and then disabled through DEVDISR, no hardware changes are required. Termination of the SerDes port should follow what is required when the port is enabled through both POR input and DEVDISR. See Note 1 for more information. If the high-speed SerDes port requires complete or partial termination, the unused pins should be terminated as described in this section. The following pins must be left unconnected (floating): • • SDn_TX[7:0] SDn_TX[7:0] The following pins must be connected to GND: • • • • SDn_RX[7:0] SDn_RX[7:0] SDn_REF_CLK SDn_REF_CLK For other directions on reserved or no-connects pins, see Section 1, “Pin Assignments and Reset States.” MPC8610 Integrated Host Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 83 Hardware Design Considerations 3.11 Guidelines for PCI Interface Termination PCI termination if PCI is not used at all. Option 1 • If PCI arbiter is enabled during POR, — All AD pins will be driven to the stable states after POR. Therefore, all ADs pins can be floating. This includes PCI_AD[31:0], PCI_C/BE[3:0], and PCI_PAR signals. — All PCI control pins can be grouped together and tied to OVDD through a single 10-kΩ resistor. — It is optional to disable PCI block through DEVDISR register after POR reset. Option 2 • If PCI arbiter is disabled during POR, — All AD pins will be in the input state. Therefore, all ADs pins need to be grouped together and tied to OV DD through a single (or multiple) 10-kΩ resistor(s) — All PCI control pins can be grouped together and tied to OVDD through a single 10-kΩ resistor — It is optional to disable PCI block through DEVDISR register after POR reset. 3.12 Thermal This section describes the thermal specifications of the MPC8610. 3.12.1 Thermal Characteristics Table 62 provides the package thermal characteristics for the MPC8610.

Ideality factor is defined as the deviation from the ideal diode equation: qVf ___ Ifw = Is e nKT – 1 Another useful equation is: KT q I IL H VH – VL = n __ ln __ Where: Ifw = Forward current Is = Saturation current V d = Voltage at diode V f = Voltage forward biased V H = Diode voltage while IH is flowing V L = Diode voltage while IL is flowing IH = Larger diode bias current IL = Smaller diode bias current q = Charge of electron (1.6 × 10 –19 C) n = Ideality factor (normally 1.0) K = Boltzman’s constant (1.38 × 10–23 Joules/K) T = Temperature (Kelvins) The ratio of IH to IL is usually selected to be 10:1. The above simplifies to the following: VH – VL = 1.986 × 10–4 × nT Solving for T, the equation becomes: nT = 4 VH – VL __________ 1.986 × 10–4 Ordering Information Ordering information for the parts fully covered by this specification document is provided in Section 4.1, “Part Numbers Fully Addressed by This Document.” 4.1 Part Numbers Fully Addressed by This Document Table 63 provides the Freescale part numbering nomenclature for the MPC8610.
