Note that during power ramp-up, before the power supplies are stable and if the I/O voltages are supplied before the core voltage, there might be a period of time that all input and output pins are actively driven and cause contention and excessive current. In order to avoid actively driving the I/O pins and to eliminate excessive current draw, apply the core voltage (VDD MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 Freescale Semiconductor 9 Power Characteristics and VDDC) before the I/O voltage (GVDD, LVDD, and OVDD) and assert PORESET before the power supplies fully ramp up. In the case where the core voltage is applied first, the core voltage supply must rise to 90% of its nominal value before the I/O supplies reach 0.7 V; see Figure 3. Once both the power supplies (I/O voltage and core voltage) are stable, wait for a minimum of 32 clock cycles before negating PORESET. Note that there is no specific power down sequence requirement for the MPC8313E. I/O voltage supplies (GVDD, LVDD, and OVDD) do not have any ordering requirements with respect to one another.

The RGMII and RTBI interfaces follow the Hewlett-Packard reduced pin-count interface for Gigabit Ethernet Physical Layer Device Specification Version 1.2a (9/22/2000). The electrical characteristics for MDIO and MDC are specified in Section 8.5, “Ethernet Management Interface Electrical Characteristics.” 8.1.1 TSEC DC Electrical Characteristics All RGMII, RMII, and RTBI drivers and receivers comply with the DC parametric attributes specified in Table 24 and Table 25. The RGMII and RTBI signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC EIA/JESD8-5. Table 24.

Note that, in general, the clock reference symbol representation for this section is based on the symbols RGT to represent RGMII and RTBI timing. For example, the subscript of tRGT represents the RTBI (T) receive (RX) clock. Note also that the notation for rise (R) and fall (F) times follows the clock symbol that is being represented. For symbols representing skews, the subscript is skew (SK) followed by the clock that is being skewed (RGT). 2. This implies that PC board design requires clocks to be routed such that an additional trace delay of greater than 1.5 ns is added to the associated clock signal. 3. For 10 and 100 Mbps, tRGT scales to 400 ns ± 40 ns and 40 ns ± 4 ns, respectively. 4. Duty cycle may be stretched/shrunk during speed changes or while transitioning to a received packet's clock domains as long as the minimum duty cycle is not violated and stretching occurs for no more than three tRGT of the lowest speed transitioned between. 5. Duty cycle reference is LVDDA/2 or LVDDB/2. 6. This symbol is used to represent the external GTX_CLK125 and does not follow the original symbol naming convention.

Each output pin of the SerDes transmitter differential pair features a 50-Ω output impedance. Each input of the SerDes receiver differential pair features 50-Ω on-die termination to XCOREVSS. The reference circuit of the SerDes transmitter and receiver is shown in Figure 33. When an eTSEC port is configured to operate in SGMII mode, the parallel interface’s output signals of this eTSEC port can be left floating. The input signals should be terminated based on the guidelines described in Section 22.5, “Connection Recommendations,” as long as such termination does not violate the desired POR configuration requirement on these pins, if applicable. When operating in SGMII mode, the TSEC_GTX_CLK125 clock is not required for this port. Instead, the SerDes reference clock is required on SD_REF_CLK and SD_REF_CLK pins. 8.3.1 DC Requirements for SGMII SD_REF_CLK and SD_REF_CLK The characteristics and DC requirements of the separate SerDes reference clock are described in Section 9, “High-Speed Serial Interfaces (HSSI).” 8.3.2 AC Requirements for SGMII SD_REF_CLK and SD_REF_CLK Table 31 lists the SGMII SerDes reference clock AC requirements.

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, tMDKHDX symbolizes management data timing (MD) for the time tMDC from clock reference (K) high (H) until data outputs (D) are invalid (X) or data hold time. Also, tMDDVKH symbolizes management data timing (MD) with respect to the time data input signals (D) reach the valid state (V) relative to the tMDC 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. This parameter is dependent on the csb_clk speed.

MII Management Interface Timing Diagram 9 High-Speed Serial Interfaces (HSSI) 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. 9.1 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 22 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 (TXn and TXn) or a receiver input (RXn and RXn). 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 TXn, TXn, RXn, and RXn 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, VOD, is defined as the difference of the two complimentary output voltages: VTXn – VTXn. 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: VRXn – VRXn. The VID value can be either positive or negative. MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 36 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) 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 × VDIFFp = 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|. 6. Differential waveform The differential waveform is constructed by subtracting the inverting signal (TXn, for example) from the non-inverting signal (TXn, 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 31 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 = (VTXn + VTXn)/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. TXn or RXn A Volts Vcm = (A + B)/2 TXn or RXn B Volts Differential Swing, V ID or VOD = A – B Differential Peak Voltage, V DIFFp = |A – B| Differential Peak-Peak Voltage, VDIFFpp = 2*VDIFFp (not shown) Figure 22. 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 and –500 mV, in other words, VOD 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 (VDIFFp-p) is 1000 mV p-p. MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 Freescale Semiconductor 37 High-Speed Serial Interfaces (HSSI) 9.2 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 input is SD_REF_CLK and SD_REF_CLK for SGMII interface. The following sections describe the SerDes reference clock requirements and some application information. 9.2.1 SerDes Reference Clock Receiver Characteristics Figure 23 shows a receiver reference diagram of the SerDes reference clocks. • The supply voltage requirements for XCOREVDD are specified in Table 1 and Table 2. • SerDes reference clock receiver reference circuit structure: — The SD_REF_CLK and SD_REF_CLK are internally AC-coupled differential inputs as shown in Figure 23. Each differential clock input (SD_REF_CLK or SD_REF_CLK) has a 50-Ω termination to XCOREVSS 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 XCOREVSS. 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 SD_REF_CLK and SD_REF_CLK inputs cannot drive 50 Ω to XCOREVSS 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. MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 38 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) 50 Ω SDn_REF_CLK Input Amp SDn_REF_CLK 50 Ω Figure 23. Receiver of SerDes Reference Clocks 9.2.2 DC Level Requirement for SerDes Reference Clocks The DC level requirement for the MPC8313E 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-to-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 DC-coupled or AC-coupled connection. — For external DC-coupled connection, as described in Section 9.2.1, “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 24 shows the SerDes reference clock input requirement for the 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 XCOREVSS. Each signal wire of the differential inputs is allowed to swing below and above the command mode voltage (XCOREVSS). Figure 25 shows the SerDes reference clock input requirement for AC-coupled connection scheme. • Single-ended mode — The reference clock can also be single-ended. The SD_REF_CLK input amplitude (single-ended swing) must be between 400 and 800 mV peak-to-peak (from Vmin to Vmax) with SD_REF_CLK either left unconnected or tied to ground. — The SD_REF_CLK input average voltage must be between 200 and 400 mV. Figure 26 shows the SerDes reference clock input requirement for the 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 MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 Freescale Semiconductor 39 High-Speed Serial Interfaces (HSSI) or AC coupled into the unused phase (SD_REF_CLK) through the same source impedance as the clock input (SD_REF_CLK) in use. SD_REF_CLK 200 mV < Input Amplitude or Differential Peak < 800 mV Vmax < 800 mV 100 mV < Vcm < 400 mV SD_REF_CLK Vmin > 0 V Figure 24. Differential Reference Clock Input DC Requirements (External DC-Coupled) 200 mV < Input Amplitude or Differential Peak < 800 mV SD_REF_CLK Vmax < Vcm + 400 mV Vcm SD_REF_CLK Vmin > Vcm – 400 mV Figure 25. Differential Reference Clock Input DC Requirements (External AC-Coupled) 400 mV < SD_REF_CLK Input Amplitude < 800 mV SD_REF_CLK 0V SD_REF_CLK Figure 26. Single-Ended Reference Clock Input DC Requirements 9.2.3 • • Interfacing With Other Differential Signaling Levels With on-chip termination to XCOREVSS, 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 a signal with too large of an amplitude and may need to be DC-biased at the clock driver output first, then followed with series attenuation resistor to reduce the amplitude, in addition to AC coupling. • MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 40 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) NOTE Figure 27 to Figure 30 are for conceptual reference only. Due to the fact that the clock driver chip's internal structure, output impedance, and termination requirements are different between various clock driver chip manufacturers, it is possible that the clock circuit reference designs provided by clock driver chip vendors are different from what is shown in the figures. They might also vary from one vendor to the other. Therefore, Freescale can neither provide the optimal clock driver reference circuits, nor guarantee the correctness of the following clock driver connection reference circuits. It is recommended that the system designer contact the selected clock driver chip vendor for the optimal reference circuits for the MPC8313E SerDes reference clock receiver requirement provided in this document. Figure 27 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 MPC8313E SerDes reference clock input’s DC requirement.

DC-Coupled Differential Connection with HCSL Clock Driver (Reference Only) Figure 28 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 MPC8313E SerDes reference clock input’s allowed range (100 to 400 mV), the AC-coupled connection scheme must be used. It assumes the LVDS output driver features a 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 29 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 the MPC8313E SerDes reference clock input’s DC requirement, AC coupling has to be used. Figure 29 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 the 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 MPC8313E SerDes3 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. Consult with the clock driver chip manufacturer to verify whether this connection scheme is compatible with a particular clock driver chip.

Single-Ended Connection (Reference Only) 9.2.4 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.

The median cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate calculations.

All output timings assume a purely resistive 50-Ω load (see Figure 34). 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.

MPC8313E Clock Subsystem MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 Freescale Semiconductor 77 Clocking The primary clock source for the MPC8313E can be one of two inputs, SYS_CLK_IN or PCI_CLK, depending on whether the device is configured in PCI host or PCI agent mode. When the device is configured as a PCI host device, SYS_CLK_IN is its primary input clock. SYS_CLK_IN feeds the PCI clock divider (÷2) and the multiplexors for PCI_SYNC_OUT and PCI_CLK_OUT. The CFG_CLKIN_DIV configuration input selects whether SYS_CLK_IN or SYS_CLK_IN/2 is driven out on the PCI_SYNC_OUT signal. The OCCR[PCICOEn] parameters select whether the PCI_SYNC_OUT is driven out on the PCI_CLK_OUTn signals. PCI_SYNC_OUT is connected externally to PCI_SYNC_IN to allow the internal clock subsystem to synchronize to the system PCI clocks. PCI_SYNC_OUT must be connected properly to PCI_SYNC_IN, with equal delay to all PCI agent devices in the system, to allow the device to function. When the device is configured as a PCI agent device, PCI_CLK is the primary input clock. When the device is configured as a PCI agent device the SYS_CLK_IN signal should be tied to VSS. As shown in Figure 57, the primary clock input (frequency) is multiplied up by the system phase-locked loop (PLL) and the clock unit to create the coherent system bus clock (csb_clk), the internal clock for the DDR controller (ddr_clk), and the internal clock for the local bus interface unit (lbc_clk). The csb_clk frequency is derived from a complex set of factors that can be simplified into the following equation: csb_clk = {PCI_SYNC_IN × (1 + ~CFG_CLKIN_DIV)} × SPMF In PCI host mode, PCI_SYNC_IN × (1 + ~CFG_CLKIN_DIV) is the SYS_CLK_IN frequency. The csb_clk serves as the clock input to the e300 core. A second PLL inside the e300 core multiplies up the csb_clk frequency to create the internal clock for the e300 core (core_clk). The system and core PLL multipliers are selected by the SPMF and COREPLL fields in the reset configuration word low (RCWL) which is loaded at power-on reset or by one of the hard-coded reset options. See Chapter 4, “Reset, Clocking, and Initialization,” in the MPC8313E PowerQUICC II Pro Integrated Processor Family Reference Manual, for more information on the clock subsystem. The internal ddr_clk frequency is determined by the following equation: ddr_clk = csb_clk × (1 + RCWL[DDRCM]) Note that ddr_clk is not the external memory bus frequency; ddr_clk passes through the DDR clock divider (÷2) to create the differential DDR memory bus clock outputs (MCK and MCK). However, the data rate is the same frequency as ddr_clk. The internal lbc_clk frequency is determined by the following equation: lbc_clk = csb_clk × (1 + RCWL[LBCM]) Note that lbc_clk is not the external local bus frequency; lbc_clk passes through the a LBC clock divider to create the external local bus clock outputs (LCLK[0:1]). The LBC clock divider ratio is controlled by LCCR[CLKDIV]. In addition, some of the internal units may be required to be shut off or operate at lower frequency than the csb_clk frequency. Those units have a default clock ratio that can be configured by a memory mapped register after the device comes out of reset. Table 64 specifies which units have a configurable clock frequency.

The SYS_CLK_IN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen such that the resulting csb_clk, MCK, LCLK[0:1], and core_clk frequencies do not exceed their respective maximum or minimum operating frequencies. The value of SCCR[ENCCM] and SCCR[USBDRCM] must be programmed such that the maximum internal operating frequency of the security core and USB modules do not exceed their respective value listed in this table. 2. The DDR data rate is 2x the DDR memory bus frequency. 3. The local bus frequency is 1/2, 1/4, or 1/8 of the lbc_clk frequency (depending on LCCR[CLKDIV]), which is in turn, 1x or 2x the csb_clk frequency (depending on RCWL[LBCM]). 20.1 System PLL Configuration The system PLL is controlled by the RCWL[SPMF] parameter.

Thermal resistance between the die and the printed-circuit board per JEDEC JESD51-8. Board temperature is measured on the top surface of the board near the package. 5. Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method 1012.1). 6. Thermal characterization parameter indicating the temperature difference between package top and the junction temperature per JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is written as Psi-JT. 21.2 Thermal Management Information For the following sections, PD = (VDD × IDD) + PI/O, where PI/O is the power dissipation of the I/O drivers. 21.2.1 Estimation of Junction Temperature with Junction-to-Ambient Thermal Resistance An estimation of the chip junction temperature, TJ, can be obtained from the equation: TJ = TA + (RθJA × PD) where: TJ = junction temperature (°C) TA = ambient temperature for the package (°C) RθJA = junction-to-ambient thermal resistance (°C/W) PD = power dissipation in the package (W) The junction-to-ambient thermal resistance is an industry standard value that provides a quick and easy estimation of thermal performance. As a general statement, the value obtained on a single layer board is appropriate for a tightly packed printed-circuit board. The value obtained on the board with the internal planes is usually appropriate if the board has low power dissipation and the components are well separated. Test cases have demonstrated that errors of a factor of two (in the quantity TJ – TA) are possible. 21.2.2 Estimation of Junction Temperature with Junction-to-Board Thermal Resistance The thermal performance of a device cannot be adequately predicted from the junction-to-ambient thermal resistance. The thermal performance of any component is strongly dependent on the power dissipation of surrounding components. In addition, the ambient temperature varies widely within the application. For many natural convection and especially closed box applications, the board temperature at the perimeter MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 Freescale Semiconductor 83 Thermal (edge) of the package is approximately the same as the local air temperature near the device. Specifying the local ambient conditions explicitly as the board temperature provides a more precise description of the local ambient conditions that determine the temperature of the device. At a known board temperature, the junction temperature is estimated using the following equation: TJ = TB + (RθJB × PD) where: TJ = junction temperature (°C) TB = board temperature at the package perimeter (°C) RθJB = junction-to-board thermal resistance (°C/W) per JESD51–8 PD = power dissipation in the package (W) When the heat loss from the package case to the air can be ignored, acceptable predictions of junction temperature can be made. The application board should be similar to the thermal test condition: the component is soldered to a board with internal planes. 21.2.3 Experimental Determination of Junction Temperature To determine the junction temperature of the device in the application after prototypes are available, the thermal characterization parameter (ΨJT) can be used to determine the junction temperature with a measurement of the temperature at the top center of the package case using the following equation: TJ = TT + (ΨJT × PD) where: TJ = junction temperature (°C) TT = thermocouple temperature on top of package (°C) ΨJT = thermal characterization parameter (°C/W) PD = power dissipation in the package (W) The thermal characterization parameter is measured per JESD51-2 specification using a 40 gauge type T thermocouple epoxied to the top center of the package case. The thermocouple should be positioned so that the thermocouple junction rests on the package. A small amount of epoxy is placed over the thermocouple junction and over about 1 mm of wire extending from the junction. The thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. 21.2.4 Heat Sinks and Junction-to-Case Thermal Resistance In some application environments, a heat sink is required to provide the necessary thermal management of the device. When a heat sink is used, the thermal resistance is expressed as the sum of a junction to case thermal resistance and a case to ambient thermal resistance: RθJA = RθJC + RθCA where: RθJA = junction-to-ambient thermal resistance (°C/W) RθJC = junction-to-case thermal resistance (°C/W) RθCA = case-to- ambient thermal resistance (°C/W) MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 84 Freescale Semiconductor Thermal RθJC is device related and cannot be influenced by the user. The user controls the thermal environment to change the case-to-ambient thermal resistance, RθCA. For instance, the user can change the size of the heat sink, the airflow around the device, the interface material, the mounting arrangement on the printed-circuit board, or change the thermal dissipation on the printed-circuit board surrounding the device. To illustrate the thermal performance of the devices with heat sinks, the thermal performance has been simulated with a few commercially available heat sinks. The heat sink choice is determined by the application environment (temperature, airflow, adjacent component power dissipation) and the physical space available. Because there is not a standard application environment, a standard heat sink is not required. Table 71.

The best method is to use thermal grease and a spring clip. The spring clip should connect to the printed-circuit board, either to the board itself, to hooks soldered to the board, or to a plastic stiffener. Avoid attachment forces which would lift the edge of the package or peel the package from the board. Such peeling forces reduce the solder joint lifetime of the package. Recommended maximum force on the top of the package is 10 lb (4.5 kg) force. If an adhesive attachment is planned, the adhesive should be intended for attachment to painted or plastic surfaces and its performance verified under the application requirements. 21.3.1 Experimental Determination of the Junction Temperature with a Heat Sink When heat sink is used, the junction temperature is determined from a thermocouple inserted at the interface between the case of the package and the interface material. A clearance slot or hole is normally required in the heat sink. Minimizing the size of the clearance is important to minimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. Because of the experimental difficulties with this technique, many engineers measure the heat sink temperature and then back calculate the case temperature using a separate measurement of the thermal resistance of the interface. From this case temperature, the junction temperature is determined from the junction to case thermal resistance. TJ = TC + (RθJC x PD) where: TJ = junction temperature (°C) TC = case temperature of the package RθJC = junction-to-case thermal resistance PD = power dissipation MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 Freescale Semiconductor 87 System Design Information 22 System Design Information This section provides electrical and thermal design recommendations for successful application of the MPC8313E SYS_CLK_IN 22.1 System Clocking The MPC8313E includes three PLLs. 1. The platform PLL (AVDD2) generates the platform clock from the externally supplied SYS_CLK_IN input in PCI host mode or SYS_CLK_IN/PCI_SYNC_IN in PCI agent mode. The frequency ratio between the platform and SYS_CLK_IN is selected using the platform PLL ratio configuration bits as described in Section 20.1, “System PLL Configuration.” 2. The e300 core PLL (AVDD1) generates the core clock as a slave to the platform clock. The frequency ratio between the e300 core clock and the platform clock is selected using the e300 PLL ratio configuration bits as described in Section 20.2, “Core PLL Configuration.” 3. There is a PLL for the SerDes block. 22.2 PLL Power Supply Filtering Each of the PLLs listed above is provided with power through independent power supply pins (AVDD1, AVDD2, and SDAVDD, respectively). The AVDD level should always be equivalent to VDD, and preferably these voltages are 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 as illustrated in Figure 58, one to each of the five AVDD 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 pin being supplied to minimize noise coupled from nearby circuits. It should be possible to route directly from the capacitors to the AV DD pin, which is on the periphery of package, without the inductance of vias. Figure 58 shows the PLL power supply filter circuits. V DD 1.0 Ω 2.2 µF 2.2 µF Low ESL Surface Mount Capacitors AV DD1 and AVDD2 Figure 58. PLL Power Supply Filter Circuit MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 88 Freescale Semiconductor System Design Information The SDAVDD signal provides power for the analog portions of the SerDes PLL. To ensure stability of the internal clock, the power supplied to the PLL is filtered using a circuit like the one shown in Figure 59. For maximum effectiveness, the filter circuit should be placed as closely as possible to the SDAVDD ball to ensure it filters out as much noise as possible. The ground connection should be near the SDAVDD ball. The 0.003-µF capacitor is closest to the ball, followed by the two 2.2-µF capacitors, and finally the 1-Ω resistor to the board supply plane. The capacitors are connected from traces from SDAVDD to the ground plane. Use ceramic chip capacitors with the highest possible self-resonant frequency. All traces should be kept short, wide, and direct. 1.0 Ω XCOREV DD SDAVDD 2.2 µF 1 2.2 µF 1 0.003 µF SDAVSS Note: 1. An 0805 sized capacitor is recommended for system initial bring-up. Figure 59. SerDes PLL Power Supply Filter Circuit Note the following: • SDAVDD should be a filtered version of XCOREVDD. • Output signals on the SerDes interface are fed from the XPADVDD power plane. Input signals and sensitive transceiver analog circuits are on the XCOREVDD supply. • Power: XPADVDD consumes less than 300 mW; XCOREVDD + SDAVDD consumes less than 750 mW. 22.3 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 MPC8313E system, and the MPC8313E 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 VDD, NVDD, GVDD, LVDD, LVDDA, and LVDDB pin of the device. These decoupling capacitors should receive their power from separate VDD, NVDD, GVDD, LVDD, LVDDA, LVDDB, and VSS 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, NVDD, GVDD, LVDD, LVDDA, and LVDDB 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 to 330 µF (AVX TPS tantalum or Sanyo OSCON). However, customers should work directly with their power regulator vendor for best values and types of bulk capacitors. MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 Freescale Semiconductor 89 System Design Information 22.4 SerDes Block Power Supply Decoupling Recommendations The SerDes block requires a clean, tightly regulated source of power (XCOREVDD and XPADVDD) to ensure low jitter on transmit and reliable recovery of data in the receiver. An appropriate decoupling scheme is outlined below. Only 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. • First, the board should have at least 10 × 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 from each SerDes supply (XCOREVDD and XPADVDD) to the board ground plane 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. 22.5 Connection Recommendations To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal level. Unused active low inputs should be tied to NVDD, GVDD, LVDD, LVDDA, or LVDDB as required. Unused active high inputs should be connected to VSS. All NC (no-connect) signals must remain unconnected. Power and ground connections must be made to all external VDD, NVDD, GVDD, LVDD, LVDDA, LVDDB, and VSS pins of the device. 22.6 Output Buffer DC Impedance The MPC8313E 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 NVDD or VSS. Then, the value of each resistor is varied until the pad voltage is NVDD/2 (see Figure 60). 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 RP is trimmed until the voltage at the pad equals NVDD/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. MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 90 Freescale Semiconductor System Design Information NVDD RN SW2 Data Pad SW1 RP VSS Figure 60. Driver Impedance Measurement The value of this resistance and the strength of the driver’s current source can be found by making two measurements. First, the output voltage is measured while driving logic 1 without an external differential termination resistor. The measured voltage is V1 = Rsource × Isource. Second, the output voltage is measured while driving logic 1 with an external precision differential termination resistor of value R term. The measured voltage is V2 = (1/(1/R1 + 1/R2)) × Isource. Solving for the output impedance gives Rsource = Rterm × (V1/V2 – 1). The drive current is then Isource = V1/Rsource. Table 72 summarizes the signal impedance targets. The driver impedance are targeted at minimum VDD, nominal NVDD, 105°C. Table 72.

See Table 1, TJ = 105° C. 22.7 Configuration Pin Muxing The MPC8313E 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 PORESET deasserts, at which time the input receiver is disabled and the I/O circuit takes on its normal function. Careful board layout with stubless connections to these pull-up/pull-down resistors coupled with the large value of the pull-up/pull-down resistor should minimize the disruption of signal quality or speed for output pins thus configured. MPC8313E PowerQUICC ™ II Pro Processor Hardware Specifications, Rev. 2.1 Freescale Semiconductor 91 System Design Information 22.8 Pull-Up Resistor Requirements The MPC8313E requires high resistance pull-up resistors (10 kΩ is recommended) on open drain type pins including I2C, Ethernet management MDIO, and IPIC (integrated programmable interrupt controller). Correct operation of the JTAG interface requires configuration of a group of system control pins as demonstrated in Figure 61. Care must be taken to ensure that these pins are maintained at a valid deasserted state under normal operating conditions because most have asynchronous behavior and spurious assertion, which give unpredictable results. Refer to the PCI 2.2 Specification, for all pull-ups required for PCI. 22.9 JTAG Configuration Signals Boundary scan testing is enabled through the JTAG interface signals. The TRST signal is optional in IEEE 1149.1, but is provided on any Freescale devices that are built on 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, systems generally assert TRST during power-on reset. Because the JTAG interface is also used for accessing the common on-chip processor (COP) function, simply tying TRST to PORESET 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 interface connects primarily through the JTAG port of the processor, with some additional status monitoring signals. The COP port requires the ability to independently assert TRST without causing PORESET. 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 61 allows the COP to independently assert HRESET or TRST, while ensuring that the target can drive HRESET as well. If the JTAG interface and COP header are not used, TRST should be tied to PORESET so that it is asserted when the system reset signal (PORESET) is asserted. The COP header shown in Figure 61 adds many benefits—breakpoints, watchpoints, register and memory examination/modification, and other standard debugger features are possible through this interface—and can be as inexpensive as an unpopulated footprint for a header to be added when needed. The COP interface has a standard header for connection to the target system, based on the 0.025" square-post, 0.100" centered header assembly (often called a Berg header). There is no standardized way to number the COP header shown in Figure 61; 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 61 is common to all known emulators.
