Interfacing With Other Differential Signaling Levels
The following list explains characteristics of interfacing with other differential signaling levels.
With on-chip termination to SGND, 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. It may need to be DC-biased at
clock driver output first and followed with series attenuation resistor to reduce the amplitude, in
addition to AC-coupling.
