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 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.
LVPECL outputs can produce a signal with too large of an amplitude and may need to be
DC-biased at the clock driver output first, then followed with series attenuation resistor to reduce
the amplitude, in addition to AC coupling.
