TxNEG1
I
Transmitter 1 Negative NRZ Data Input
.
In dual-rail mode, this signal is the n-rail data input for transmitter 1.
In single-rail mode, this pin can be left unconnected.
N
OTE
:
Internally pulled -up with a 50k
resistor.
24
RxLOS1
O
Receiver 1 Loss of Signal
.
This signal is asserted "High" to indicate loss of signal at the receive input.
25
RxClk1
O
Receiver 1 Clock Output.
26
RxPOS1/
RData1
O
Receiver 1 Positive Data Output:
In dual-rail mode, this signal is the receive P-rail output data.
Receiver 1 NRZ Data Output:
In single-rail mode, this signal is the receive output data.
27
RxNEG1/LCV1
O
Receiver 1 Negative Data Output:
In dual-rail mode, n-rail data are sent to the framer.
Line Code Violation Output:
In single-rail mode, this signal output "High" for one receive clock cycle to indi-
cate 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".
