Table 2 presents the signal list by signal name. When designing a board, make sure that the power rail for each signal is appropriately considered. The specified power rail must be tied to the voltage level specified in this document if any of the related signal functions are used (active) NOTE The information in Table 1 distinguishes among three concepts. First, the power pins are the balls of the device package used to supply specific power levels for different device subsystems (as opposed to signals). Second, the power rails are the electrical lines on the board that transfer power from the voltage regulators to the device. They are indicated here as the reference power rails for signal lines; therefore, the actual power inputs are listed as N/A with regard to the power rails. Third, symbols used in these tables are the names for the voltage levels (absolute, recommended, and so on) and not the power supplies themselves. Table 1.

Signal function during power-on reset is determined by the RCW source type. Selection of RapidIO, SGMII, CPRI, and PCI Express functionality during normal operation is configured by the RCW bit values. Selection of the GPIO function and other functions is done by GPIO register setup. For signals with GPIO functionality, the open-drain and internal 20 KΩ pull-up resistor can be configured by GPIO register programming. For configuration details, see the GPIO chapter in the MSC8157 Reference Manual. NC signals should be disconnected for compatibility with future revisions of the device. Non-user signals are reserved for manufacturing and test purposes only. The assigned signal name is used to indicate whether the signal must be unconnected (Reserved), pulled down (VSS or SXCVSS), or pulled up (VDD). Pin types are: Ground = all VSS connections; Power = all VDD connections; I = Input; O = Output; I/O = Input/Output; NC = not connected; non-user = connect as specified under Signal Name. Connect power inputs to the power supplies via external filters. See the MSC8157 Design Checklist (AN4110) for details. Table 2.

For additional information, see the MSC8157 Reference Manual. 3.1 Maximum Ratings In calculating timing requirements, adding a maximum value of one specification to a minimum value of another specification does not yield a reasonable sum. A maximum specification is calculated using a worst case variation of process parameter values in one direction. The minimum specification is calculated using the worst case for the same parameters in the opposite direction. Therefore, a “maximum” value for a specification never occurs in the same device with a “minimum” value for another specification; adding a maximum to a minimum represents a condition that can never exist. Table 3 describes the maximum electrical ratings for the MSC8157. Table 3.

This section and its subsections describe the common portion of the SerDes DC, including the DC requirements for the SerDes reference clocks and the SerDes data lane MSC8157 Six-Core Digital Signal Processor Data Sheet, Rev. 3 Freescale Semiconductor 55 Electrical Characteristics transmitter (Tx) and receiver (Rx) reference circuits. The data lane circuit specifications are specific for each supported interface, and they have individual subsections by protocol. The selection of individual data channel functionality is done via the Reset Configuration Word High Register (RCWHR) SerDes Protocol selection fields (S1P and S2P). Specific AC electrical characteristics are defined in Section 3.6.2, “HSSI AC Timing Specifications.” 3.5.2.1 Signal Term Definitions The SerDes interface uses differential signaling to transfer data across the serial link. This section defines terms used in the description and specification of differential signals. Figure 2 shows how the signals are defined in addition to the waveform for either a transmitter output (SD_[A–J]_TX and SD_[A–J]_TX) or a receiver input (SD_[A–J]_RX and SD_[A–J]_RX). Each signal swings between X volts and Y volts where X > Y. SD_[A–J]_TX or SD_[A–J]_RX X Volts Vcm = (X + Y)/2 SD_[A–J]_TX or SD_[A–J]_RX Y Volts Differential Swing, VID or VOD = X – Y Differential Peak Voltage, VDIFFp = |X – Y| Differential Peak-Peak Voltage, VDIFFpp = 2 × VDIFFp (not shown) Figure 2. Differential Voltage Definitions for Transmitter/Receiver Using this waveform, the definitions are listed in Table 10. To simplify the illustration, the definitions assume that the SerDes transmitter and receiver operate in a fully symmetrical differential signaling environment. Table 10. Differential Signal Definitions Term Definition Single-Ended Swing The transmitter output signals and the receiver input signals SD[A–J]_TX, SD_[A–J]_TX, SD_[A–J]_RX and SD_[A–J]_RX each have a peak-to-peak swing of X – Y volts. This is also referred to as each signal wire’s single-ended swing. Differential Output Voltage, VOD (or The differential output voltage (or swing) of the transmitter, VOD, is defined as the difference of the two complimentary output voltages: VSD_[A–J]_TX – VSD[A–J]_TX. The VOD value can Differential Output Swing) be either positive or negative. 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: VSD_[A–J]_RX – VSD_[A–J]_RX. The VID value can be either positive or negative. MSC8157 Six-Core Digital Signal Processor Data Sheet, Rev. 3 56 Freescale Semiconductor Electrical Characteristics Table 10. Differential Signal Definitions (continued) Term Definition Differential Peak Voltage, VDIFFp The peak value of the differential transmitter output signal or the differential receiver input signal is defined as the differential peak voltage, VDIFFp = |X– Y| 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 × VDIFFp = 2 × |(A – B)| volts, which is twice the 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_[A–J]_TX, for example) from the non-inverting signal (SD_[A–J]_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 2 as an example for differential waveform. Common Mode Voltage, Vcm The common mode voltage is equal to 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 = (VSD_[A–J]_TX + VSD_[A–J]_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. It may be different between the receiver input and driver output circuits within the same component. It is also referred to as the DC offset on some occasions. To illustrate these definitions using real values, consider the example of a current mode logic (CML) transmitter that has a common mode voltage of 2.25 V and outputs, TD and TD. If these outputs have a swing from 2.0 V to 2.5 V, the peak-to-peak voltage swing of each signal (TD or TD) is 500 mV p-p, which is referred to as the single-ended swing for each signal. Because the differential signaling environment is fully symmetrical in this example, the transmitter output differential swing (VOD) has the same amplitude as each signal single-ended swing. The differential output signal ranges between 500 mV 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. 3.5.2.2 SerDes Reference Clock Receiver Characteristics 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 clock inputs are SD_REF_CLK1/SD_REF_CLK1 or SD_REF_CLK2/SD_REF_CLK2. Figure 3 shows a receiver reference diagram of the SerDes reference clocks. 50 Ω SD_REF_CLK[1–2] Input Amp SD_REF_CLK[1–2] 50 Ω Figure 3. Receiver of SerDes Reference Clocks MSC8157 Six-Core Digital Signal Processor Data Sheet, Rev. 3 Freescale Semiconductor 57 Electrical Characteristics The characteristics of the clock signals are as follows: • • • • The supply voltage requirements for VDDSXC are as specified in Table 4. The SerDes reference clock receiver reference circuit structure is as follows: — The SD_REF_CLK[1–2] and SD_REF_CLK[1–2] are internally AC-coupled differential inputs as shown in Figure 3. Each differential clock input (SD_REF_CLK[1–2] or SD_REF_CLK[1–2] has on-chip 50-Ω termination to SXCVSS 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 descriptions below for detailed requirements. The maximum average current requirement 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 because 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 GNDSXC. 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 mA 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[1–2] and SD_REF_CLK[1–2] inputs cannot drive 50 Ω to GNDSXC DC or the drive strength of the clock driver chip exceeds the maximum input current limitations, it must be AC-coupled externally. The input amplitude requirement is described in detail in the following sections. 3.5.2.3 SerDes Transmitter and Receiver Reference Circuits Figure 4 shows the reference circuits for SerDes data lane transmitter and receiver. 50 Ω SD_[A–J]_TX SD_[A–J]_RX 50 Ω Transmitter Receiver 50 Ω SD_[A–J]_TX SD_[A–J]_RX 50 Ω Note: The [A–J] indicates the specific SerDes lane. Each lane can be assigned to a specific protocol by the RCW assignments at reset (see the MSC8157 Reference Manual for details). External AC coupling capacitors are required for all protocols for all lanes. Figure 4. SerDes Transmitter and Receiver Reference Circuits 3.5.2.4 Equalization With the use of high-speed serial links, the interconnect media causes degradation of the signal at the receiver and produces effects such as inter-symbol interference (ISI) or data-dependent jitter. This loss can be large enough to degrade the eye opening at the receiver beyond that allowed by the specification. To offset a portion of these effects, equalization can be used. The following is a list of the most commonly used equalization techniques: • Pre-emphasis on the transmitter MSC8157 Six-Core Digital Signal Processor Data Sheet, Rev. 3 58 Freescale Semiconductor Electrical Characteristics • • A passive high-pass filter network placed at the receiver, often referred to as passive equalization The use of active circuits in the receiver, often referred to as adaptive equalization 3.5.3 DC-Level Requirements for SerDes Interfaces The following subsections define the DC-level requirements for the SerDes reference clocks, the PCI Express data lines, the Serial RapidIO data lines, the CPRI data lines, and the SGMII data lines. 3.5.3.1 DC-Level Requirements for SerDes Reference Clocks The DC-level requirement for the 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 mV and 1600 mV differential peak-peak (or between 200 mV and 800 mV differential peak). In other words, each signal wire of the differential pair must have a single-ended swing of less than 800 mV and greater than 200 mV. This requirement is the same for both external DC-coupled or AC-coupled connection. — For an external DC-coupled connection, the maximum average current requirements sets the requirement for average voltage (common mode voltage) as between 100 mV and 400 mV. Figure 5 shows the SerDes reference clock input requirement for DC-coupled connection scheme. SD_REF_CLK[1–2] 200 mV < Input Amplitude or Differential Peak < 800 mV Vmax < 800 mV 100 mV < Vcm < 400 mV Vmin > 0 V SD_REF_CLK[1–2] Figure 5. Differential Reference Clock Input DC Requirements (External DC-Coupled) — For an external AC-coupled connection, there is no common mode voltage requirement for the clock driver. Because 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 GNDSXC. Each signal wire of the differential inputs is allowed to swing below and above the command mode voltage GNDSXC. Figure 6 shows the SerDes reference clock input requirement for AC-coupled connection scheme. MSC8157 Six-Core Digital Signal Processor Data Sheet, Rev. 3 Freescale Semiconductor 59 Electrical Characteristics 200 mV < Input Amplitude or Differential Peak < 800 mV SD_REF_CLK[1–2] Vmax < Vcm + 400 mV Vcm Vmin > Vcm – 400 mV SD_REF_CLK[1–2] Figure 6. Differential Reference Clock Input DC Requirements (External AC-Coupled) • Single-Ended Mode — The reference clock can also be single-ended. The SD_REF_CLK[1–2] input amplitude (single-ended swing) must be between 400 mV and 800 mV peak-peak (from VMIN to VMAX) with SD_REF_CLK[1–2] either left unconnected or tied to ground. — The SD_REF_CLK[1–2] input average voltage must be between 200 and 400 mV. Figure 7 shows the SerDes reference clock input requirement for single-ended signaling mode. — To meet the input amplitude requirement, the reference clock inputs may 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 (SD_REF_CLK[1–2]) through the same source impedance as the clock input (SD_REF_CLK[1–2]) in use. 400 mV < SD_REF_CLK[1–2] Input Amplitude < 800 mV SD_REF_CLK[1–2] 0V SD_REF_CLK[1–2] Figure 7.

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. All MCK/MCK referenced measurements are made from the crossing of the two signals. ADDR/CMD includes all DDR SDRAM output signals except MCK/MCK, MCS, and MDQ/MECC/MDM/MDQS. 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 is typically set to the same delay as the clock adjust in the CLK_CNTL register. The timing parameters listed in the table assume that these two parameters have been set to the same adjustment value. See the MSC8157 Reference Manual for a description and understanding of the timing modifications enabled by use of these bits. 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 MSC8157. At recommended operating conditions with VDDDDR (1.5 V) ± 5%. NOTE For the ADDR/CMD setup and hold specifications in Table 30, it is assumed that the clock control register is set to adjust the memory clocks by ½ applied cycle.

Limits are from PCI Express CEM Rev 2.0. Measured from –200 mV to +200 mV on the differential waveform (derived from SD_REF_CLKn minus SD_REF_CLKn). The signal must be monotonic through the measurement region for rise and fall time. The 400 mV measurement window is centered on the differential zero crossing. See Figure 13. Measurement taken from differential waveform. Measurement taken from single-ended waveform. Matching applies to rising edge for SD_REF_CLKn and falling edge rate for SD_REF_CLKn. It is measured using a 200 mV window centered on the median cross point where SD_REF_CLKn rising meets SD_REF_CLKn falling. The median cross point is used to calculate the voltage thresholds that the oscilloscope uses for the edge rate calculations. The rising edge rate of SD_RF_CLKn should be compared to the falling edge rate of SD_REF_CLKn; the maximum allowed difference should not exceed 20% of the slowest edge rate. See Figure 14. REF_CLK jitter must be less than 0.05 UI when measured against a Golden PLL reference. The Golden PLL must have a maximum baud rate bandwidth greater than 1667, with a maximum 20 dB/dec rolloff down to a baud rate of 16.67 with no peaking around the corner frequency.

The jitter median describes the point in time where the number of jitter points on either side is approximately equal as opposed to the averaged time value. If the clocks to the Rx and Tx are not derived from the same reference clock, the Tx UI recovered from 3500 consecutive UI must be used as the reference for the eye diagram. It is recommended that the recovered Tx UI is calculated using all edges in the 3500 consecutive UI interval with a fit algorithm using a minimization merit function.
