RNEG3/LCV3
O
Receiver 3 Negative Data Output:
In dual-rail mode, this signal is the receive n-rail output data.
Line Code Violation Output:
In single-rail mode, this signal output High for one clock cycle to indicate a
code violation is detected in the received data. If AMI coding is selected,
every bipolar violation received will cause this pin to go High.
