Primary Receive Serial Data Input
The receive serial data stream of 2.488Gbps is applied to the
primary input pins if RXSEL is "Low". In Forward Error Correc-
tion, the receive serial data stream is 2.666Gbps.

Disable Receive Output Data Upon LOS
Hardware Mode
If this pin is pulled "High", the receive output
data will automically pull "Low" when a LOS condition occurs.
"Low" = Disabled
