High-Speed Serial Interfaces (HSSI)
— 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-
or AC-coupled into the unused phase (SD_REF_CLK) through the same source impedance as
the clock input (SD_REF_CLK) in use.

Interfacing With Other Differential Signaling Levels
With on-chip termination to SGND_SRDSn (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.
