In-Circuit Test Input:
Setting this pin "Low" causes all digital and analog outputs to go into a high-
impedance state to allow for in-circuit testing. For normal operation, tie this pin
"High".
NOTE: This pin is internally pulled “High".

Hardware Mode: MUTE-upon-LOS Enable Input
Host Mode: Interrupt Ouput:
In Hardware Mode, setting pin “High” configures all three channels to Mute the
recovered data on the RPOS_n and RNEG_n whenever one of the channels
declares an LOS condition. RPOS_n and RNEG_n outputs are pulled “Low”.
Muting of the output data can be configured/controlled on a per channel basis
in Host Mode.
NOTE:
If the XRT75L04 is configured in HOST mode, this pin functions as INT
pin (please refer to the pin description for the Microprocessor Interface).

This input pin along with RLB_n configures different Loop-Back modes.
A "High" on this pin with RLB_n set to "Low" configures Channel_n to operate
in the Analog Local Loop-back Mode.
A "High" on this pin with RLB_n set to "High" configures Channel_n to operate
in the Digital Local Loop-back Mode.
NOTE:
This input pin is ignored and should be connected to GND if the
XRT75L04 is operating in the HOST Mode.

the Remote Loop-back Mode.
A "High" on this pin with LLB_n set to "High" configures Channel_n to operate
in the Digital Local Loop-back Mode.
NOTE:
This input pin is ignored and should be connected to GND if the
