0; LLOOP_0 (General Purpose) Output Pin:
The function of this input pin depends upon whether or not
theSTS-3/STM-1 Telecom Bus Interface associated with Chan-
nel 0 is enabled.
If STS-3/STM-1 Telecom Bus (Channel 0) has been enabled
- STS-3/STM-1 Receive Telecom Bus Clock Output - Chan-
nel 0; STS3RxD_CLK_0:
All signals, which is output via the Receive Telecom Bus -
Channel 0 is clocked out upon the rising edge of this clock sig-
nal. This includes the following signals.
•
•
•
•
•
This clock signal will operate at 19.44MHz.
If STS-3/STM-1 Telecom Bus (Channel 0) is disabled -
LLOOP_0 (General Purpose) Output Pin:
This output pin can be used as a general purpose output pin.
The state of this output pin can be controlled by writing the
appropriate value into Bit 0 (LLOOP) within the Line Interface
Drive Register associated with Channel 0 (Indirect Address =
0x1E, 0x80), (Direct Address = 0x1F80).

:
LLOOP_0 because one possible application is to tie
this output pin to an LLOOP (Local Loop-back) input
pin from one of Exar's XRT73L0X/XRT75L0X DS3/E3/
STS-1 LIU devices. However, this output pin, and the
corresponding register bit can be used for any
purpose.
For Product Legacy purposes, this pin is called
