Freescale Semiconductor
— 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-
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
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.

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
