Description
Loop Enable 1. If driven high the specified loopback mode will be enabled for
channel 1. Otherwise normal operation will continue.
Loop Enable 2. If driven high the specified loopback mode will be enabled for
channel 2. Otherwise normal operation will continue.
Transmitter 1 Negative Data In. Negative data input in NRZ or RZ format for
transmitter 1.
Transmitter 1 Positive Data In. Positive data input in NRZ or RZ format for
transmitter 1.
Transmitter 1 Clock Input. Apply logic one when RZ signals are supplied to
data inputs.
Transmitter 2 Negative Data In. Negative data input in NRZ or RZ format for
transmitter 2.
Transmitter 2 Positive Data In. Positive data input in NRZ or RZ format for
transmitter 2.
Transmitter 2 Clock Input. Apply logic one when RZ signals are supplied to
data inputs.
Analog V
Loss of Signal Voltage Select. Apply logic one to select LOS voltage level
appropriate for 120 balanced receiver operation. Connect to ground to
choose LOS voltage for 75 unbalanced operation.
No Charge.
Transmitter 2 Output Enable. If asserted the transmitter 2 output drivers are
enabled. High-Z otherwise.
