O
Line Code Violation - Channel (n):
The function of this pin is dependent on whether the XRT73LC04A is in
the Hardware or HOST Mode (HOST/HW) and if CS/(SR/DR) is set
“High”.
Hardware Mode
Line Code Violation:
When CS/(SR/DR) is set “High”, (Single-Rail operation), the B3ZS/HDB3
Encoder/Decoder is activated and the Line Code Violation signal is out-
put on this pin.
HOST Mode
Receive Negative Data:
Writing a “1” to (SR/DR)_(n) bit of the Command Register configures the
Single-Rail Mode and activates LCV_(n).
If the B3ZS/HDB3 Decoder is enabled then the zero suppression pat-
terns in the incoming line signal (such as: "00V", "000V", "B0V", "B00V")
is not reflected at this output.

ICT
I
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. This pin should be
set to "High" for normal operation.
This pin is internally pulled "High".
75
LOSTHR
I
Loss of Signal Threshold Control
:
Forcing the LOSTHR pin to GND or VDD provides two settings. This pin
must be set to a “High” or “Low” level upon power up and should not be
changed during operation.
This pin is only applicable during DS3 or STS-1 operations.

Local Loop-back - Channel (n)
:
This input pin along with RLB_(n) dictates which Loop-Back mode Chan-
nel (n) is operating in.
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) also being set to "High" configures
Channel (n) to operate in the Digital Local Loop-Back Mode.
N
OTE
:
This pin is ignored and should be tied to GND if the XRT73LC04A
is going to be operating in the HOST Mode.

Remote Loop-Back - Channel (n):
This input pin in conjunction with LLB_(n) dictates which Loop-Back
mode Channel (n) is operating in.
A "High" on this pin with LLB_(n) being set to "Low" configures Channel
(n) to operate in the Remote Loop-Back Mode.
A "High" on this pin with LLB_(n) also being set to "High" configures
Channel (n) to operate in the Digital Local Loop-Back Mode.
N
OTE
:
This pin is ignored and should be tied to GND if the XRT73LC04A
is going to be operating in the HOST Mode.
