LOSMUTEN
I
MUTE-upon-LOS Enable Input (Hardware Mode):
This input pin is use to configure the XRT73L04A, while it is operating in
the Hardware Mode, to MUTE the recovered data via the RPOS_(n),
RNEG_(n) output pins whenever one of the Channels declares an LOS
conditions.
Setting this input pin “High" configures all Channels to automatically pull
the RPOS_(n) and RNEG_(n) output pins “Low” whenever it is declaring
an LOS condition, thereby MUTing the data being output to the Terminal
Equipment.
Setting this input pin "Low" configures all Channels to NOT automatically
MUTE the recovered data whenever an LOS condition is declared.
N
OTES
:
1. This pin is ignored and should be tied to GND if the XRT73L04A
is going to be operating in the HOST Mode.
2. This pin is internally pulled "Low".

CS/
SR/DR
I
Microprocessor Serial Interface - Chip Select Input/Encoder-
Decoder Disable Input:
The function of this pin depends upon whether the XRT73L04A is oper-
ating in the HOST Mode or in the Hardware Mode.
HOST Mode Operation - Chip Select Input:
The Local Microprocessor must assert this pin to "0" in order to enable
communication with the XRT73L04A via the Microprocessor Serial Inter-
face.
N
OTE
:
This pin is internally pulled "High".

SClk/(RxOFF)
I
Microprocessor Serial Interface Clock Signal/Receiver Shut OFF
Input:
The function of this pin depends upon:
HOST Mode - Microprocessor Serial Interface Clock Signal:
This signal is used to sample the data on the SDI pin on the rising edge
of this signal. During Read operations the Microprocessor Serial Inter-
face updates the SDO output on the falling edge of this signal.
Hardware Mode - Receiver Shut OFF input:
Setting this input pin "High" shuts off all of the Receiver Sections. Set-
ting this input pin "Low" enables all of the Receive Sections for full oper-
ation.
71
SDI/E3_1
I
Serial Data Input for the Microprocessor Serial Interface
This pin has a dual function.
HOST Mode:
To read or write data into the Command Registers over the Microproces-
sor Serial Interface, apply the Read/Write bit, the Address Values of the
Command Registers and Data Value to be written during Write Opera-
tions to this pin.
This input is sampled on the rising edge of the SClk pin.
