Protected Monitoring/Address Select Inputs.
Hardware Mode
In hardware mode, these pins are used to select a specific port for non
intrusive monitoring. During protection monitoring receiver 0 inputs are
internally connected to a specific transmit or receive port. Receiver 0 routes
the data from the selected port to its data and clock recovery circuits. The
data on the monitor port can be routed to TTIP0/TRING0 by activating the
remote loopback for channel 0. In addition, the recovered clock and data can
be observed at the RCLK0/RPOS0/RNEG0 outputs.
If A0, A1, and A2 are Low, the LXT380 is configured as octal line transceiver
without monitoring capability.
Transmitter monitoring is not supported when the respective channel is set to
analog loopback mode.
Host Mode
In non-multiplexed host mode, these pins function as non-multiplexed
address pins.
