To enable this feature, access the Microprocessor Se-
rial Interface and write a “1” into the LOSMUT bit-field
in Command Register 3.

The XRT73LC00A automatically declares an LOS
Condition any time it has been configured to operate in
either the Analog Local Loop-Back or Digital Local Loop-
Back Modes. Muting -upon -LOS must be disabled prior to
configuring the device to operate in either of these local
Loop-Back modes.
levels and routes it to the Receiving Terminal Equip-
ment via the RPOS, RNEG, RCLK1 and RCLK2 out-
put pins.
The XRT73LC00A can deliver the recovered data and
clock information to the Receiving Terminal in either a
Single-Rail or Dual-Rail format.
Routing Dual-Rail Format Data to the Receiving
Terminal Equipment
Whenever the XRT73LC00A delivers Dual-Rail for-
mat to the Terminal Equipment it does so via the fol-
lowing output signals.

Figure 24 illustrates the typical interface for the trans-
mission of data in a Dual-Rail Format from the Re-
ceive Section of the XRT73LC00A to the Receiving
Terminal Equipment.
The manner that the LIU transmits Dual-Rail data to
the Receiving Terminal Equipment is described below
and illustrated in Figure 25. The XRT73LC00A typi-
cally updates the data on the RPOS and RNEG out-
put pins on the rising edge RCLK1 (or RCLK2).
