The supply voltage requirements for XV
SerDes Reference Clock Receiver Reference Circuit Structure
— The SDn_REF_CLK and SDn_REF_CLK are internally AC-coupled differential inputs as
— 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 SDn_REF_CLK and SDn_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 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 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.
SGND DC, or it exceeds the maximum input current limitations, then it must be AC-coupled
off-chip.
