CS/(SR/DR)
I
Microprocessor Serial Interface - Chip Select Input/Encoder-
Decoder Disable Input:
The function of this pin depends upon whether the XRT73L04 is operat-
ing 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 XRT73L04 via the Microprocessor Serial Inter-
face.
N
OTE
:
This pin is internally pulled "High".
Hardware Mode - Receive Output Single-Rail/Dual-Rail Select:
In Hardware Mode, setting this pin “High” selects Single-Rail Mode
operation for all channels. In Single-Rail Mode, TNData(n) Input must be
Grounded to enable HDB3/B3ZS Encoding and Decoding.
Tie this pin “Low” to select Dual-Rail Mode for both Transmit and Receive
channels.

SClk/(RxOFF)
I
Microprocessor Serial Interface Clock Signal/Receiver Shut OFF
Input- Channel 1:
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 - All Channel Receiver Shut OFF input pin:
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.

SDI/(E3_Ch1)
I
Serial Data Input for the Microprocessor Serial Interface/E3_Mode
Select - Channel 1
The function of this input depends upon:
HOST Mode - Serial Data Input for the Microprocessor Serial Inter-
face:
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.
Hardware Mode Operation - E3 Mode Select - Channel 1:
This input pin is used to configure Channel 1 of the XRT73L04 to oper-
ate in the E3 or STS-1/DS3 Modes. Setting this input pin to "High" con-
figures Channel 1 to operate in the E3 Mode. Setting it "Low" configures
Channel 1 to operate in either the DS3 or STS-1 Modes, depending
upon the state of the STS-1/DS3_Ch1 input pin.
N
OTE
:
This pin is internally pulled “Low” when XRT73L04 is in the Hard-
ware Mode.
