DS3 Reference Clock Input for the Jitter Attenuator within the DS3/
E3 Mapper Block:
To operate any of the channels of the XRT94L31 in the DS3 Mode, apply
a clock signal with a frequency of 44.736±20ppm to this input pin.
This input pin functions as the timing reference for the DS3/E3/STS-1 Jit-
ter Attenuator (within the DS3/E3 Mapper block) for DS3 applications.
For DS3 Applications, the DS3/E3 Framer block will use this input clock
signal, as a timing source in order to transmit the DS3 AIS Pattern, in the
Egress Direction (e.g., from the XRT94L31 to the DS3/E3/STS-1 LIU
IC).
If the user does not intend to operate any of the three (3) channels in the
DS3 Mode, or if the user intends to configure the XRT94L31 to operate
in the SFM Mode, connect this input pin to GND.
