Transmit All Ones Select - Channel 0:
Transmit All Ones Select - Channel 1:
A “High" on this pin causes the Transmitter Section of Channel_n to generate
and transmit a continuous AMI all “1’s” pattern onto the line. The frequency of
this “1’s” pattern is determined by TxClk_n.
NOTES:
1. This input pin is ignored if the XRT73L02M is operating in the HOST
Mode and should be tied to GND.
2. Analog Loopback and Remote Loopback have priority over request.
3. This pin is internally pulled down.

Receive Equalization Enable Input - Channel 0:
Receive Equalization Enable Input - Channel 1:
Setting this input pin "High" enables the Internal Receive Equalizer of
Channel_n. Setting this pin "Low" disables the Internal Receive Equalizer.
NOTES:
1. This input pin is ignored and should be connected to GND if the
XRT73L02M is operating in the HOST Mode
2. This pin is internally pulled down.

I
Hardware Mode: Receiver Turn ON Input
Host Mode: Serial Data Input:
Function of this pin depends on whether the XRT73L02M is configured to oper-
ate in Hardware mode or Host mode.
In Hardware mode, setting this input pin “High” turns on and enables the
Receivers of all the channels.
NOTES:
1. If the XRT73L02M is configured in HOST mode, this pin functions as
SDI input pin (please refer to the pin description for Microprocessor
Interface)
2. This pin is internally pulled down.

RxMON/
SDO
I
Hardware Mode: Receive Monitoring Mode
Host Mode: Serial Data Output:
In Hardware mode, when this pin is tied “High” all 2 channels configure into
monitoring channels. In the monitoring mode, the Receiver is capable of moni-
toring the signals with 20 dB flat loss plus 6 dB cable attenuation. This allows
monitoring very weak signal before declaring LOS.
In HOST Mode each channel can be independently configured to be a monitor-
ing channel by setting the bits in the channel control registers.
NOTE: If the XRT73L02M is configured in HOST mode, this pin functions as
SDO pin (please refer to the pin description for the Microprocessor Interface).
