RLCV/
I/O
Receive Line Code Violation Indication
(RLCV). When the E1XC is
configured to receive single-rail data,
this input may be enabled to be
sampled on the rising or falling edge
of RCLKI.
SDN
Sliced Negative Line Pulse (SDN).
This pin becomes an output when the
receive analog line interface is
powered up. A positive pulse on the
SDN output corresponds to the
sampled negative pulse excursion on
the RAS input.
RCLKI
Input

Receive Line Clock Input (RCLKI).
This input is an externally recovered
2.048 MHz line clock that may be
enabled to sample the RDP and RDN
inputs on its rising or falling edge
when the input format is enabled for
dual-rail NRZ; or to sample the RDD
and RLCV inputs on its rising or falling
edge when the input format is enabled
for single-rail.

Receive Analog Signal (RAS). This
analog input samples the AC signal
on an external isolation transformer. It
is connected to the positive lead of the
transformer secondary through a
passive attenuation network.
Receive Reference (REF). This
analog bidirectional pin provides DC
bias to an external isolation
transformer. It is connected to the
negative lead of the transformer
secondary and to a decoupling
capacitor to RAVS.
