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