High-Speed Serial Interfaces (HSSI)

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.

The supply voltage requirements for XCOREV
SerDes reference clock receiver reference circuit structure:
— The SD_REF_CLK and SD_REF_CLK are internally AC-coupled differential inputs as shown
— 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
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
— This current limitation sets the maximum common mode input voltage to be less than 0.4 V
— If the device driving the SD_REF_CLK and SD_REF_CLK inputs cannot drive 50 Ω to
The input amplitude requirement. This requirement is described in detail in the following sections.

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.
(0.4 V/50 = 8 mA) while the minimum common mode input level is 0.1 V above XCOREV
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.
