10.2.3
With on-chip termination to XCOREVSS, the differential reference clocks inputs are high-speed current
steering logic (HCSL) compatible and DC coupled.
Many other low voltage differential type outputs like low-voltage differential signaling (LVDS) can be
used but may need to be AC-coupled due to the limited common mode input range allowed (100–400 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, in addition to
AC-coupling.
