Description
Receiver 4 Negative Data Out. Negative data output in NRZ or RZ format for
receiver 4.
Receive V
Loop Mode 4. If driven high the loopback mode of channel 4 will be set to re-
mote loop. Otherwise theloopback mode will remain at local loop. The
actual loopback will be activated when the LOOPEN4 is asserted.
Loop Mode 3. If driven high the loopback mode of channel 3 will be set to re-
mote loop. Otherwise the loopback mode will remain at local loop. The
actual loopback will be activated when the LOOPEN3 is asserted.
Receiver 4 Input. Receiver 4 bipolar input connected to coupling capacitor or
pulse transformer.
Receiver 4 Loss Of Signal. Asserted during LOS condition. Clear otherwise.
Receiver 3 Loss Of Signal. Asserted during LOS condition. Clear otherwise.
Receiver 3 Input. Receiver 3 bipolar input connected to coupling capacitor or
pulse transformer.
Monitor Channel Select 0. Select line, used to select a channel for monitoring
using the MOUT pin based on the following assignment:
Note
The monitoring is only done on the NRZ data output signals from the receiver or from the
transmitter line side.
Monitor Channel Select 1. See table above.
Receive Ground.
Receive Ground.
Monitor Channel Select 2. See table above.
Receiver 2 Input. Receiver 2 bipolar input connected to coupling capacitor or
pulse transformer.
Receiver 1 Loss Of Signal. Asserted during LOS condition. Clear otherwise.
Receiver 2 Loss Of Signal. Asserted during LOS condition. Clear otherwise.
Receiver 1 Input. Receiver 1 bipolar input connected to coupling capacitor or
pulse transformer.
Loop Mode 2. If driven high the loopback mode of channel 2 will be set to re-
mote loop. Otherwise the loopback mode will remain at local loop. The
actual loopback will be activated when the LOOPEN2 is asserted.
