Differential inputs for each channel from its
respective receive coax line. The RX expects
balanced differential inputs, usually
achieved using a 1:1 transformer.
The inputs are internally DC biased to 1.9 V.
Differential, coax-driver balanced outputs
for pulse-shaped AMI B3ZS/HDB3 encoded
waveforms for each channel.
These pins should be connected to the
primary side of the 1:1 transformer through
two backmatch resistors (see
CX28331/CX28332/CX28333
