XRT73L00
E3/DS3/STS-1 LINE INTERFACE UNIT
REV. 1.2.0

To configure the XRT73L00 to invert the RCLK1 out-
put signal, the XRT73L00 must be operating in the
HOST Mode. This configuration can be implemented
by accessing the Microprocessor Serial Interface
block and writing a “1” into the RCLK1INV bit-field in
Command Register CR3 to invert RCLK1.
The RCLK2 output signal can also be inverted when
the XRT73L00 is operating in the Hardware Mode by
setting the RCLK2INV input pin “High”.
3.7.1
Routing Single-Rail Format data (Binary
Data Stream) to the Receive Terminal Equipment
To route Single-Rail format data (e.g., a binary data
stream) from the Receive Section of the XRT73L00 to
the Receiving Terminal Equipment, do the following:
A.
configure the XRT73L00 to operate in the HOST
Mode and
B.
access the Microprocessor Serial Interface and
write a “1” into the RNRZ bit-field in Command
Register CR3.
After these steps are taken, the XRT73L00 outputs
Single-Rail data to the Receiving Terminal Equipment
via the RPOS and RCLK1 (or RCLK2) output pins as
illustrated in Figure 26 and Figure 27.

The RNEG output pin is internally tied to GND
whenever this feature is enabled.
