Line clock input should be
connected to a 44.736 MHz
source in DS3 mode or to a
34.368 MHz source in E3
mode, derived from incoming
receive data.
it is the positive data input. In
unipolar mode it is the NRZ
data input. Sampled on the
rising/falling (programmable)
edge of the receiver input
clock (LINECK).
it is the negative data input. In
unipolar mode, it is the line
code violation input for LCV
counting (if unused tie low).
Sampled on the rising/falling
(programmable) edge of the
receiver input clock (LINECK).
