2 CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT
XRT7302
REV. 1.1.6

Inverting the RxClk(n) signals via the Hardware
Mode
Setting the RxClkINV input pin “High" inverts all the
RxClk(n) output signals.
3.7.2
Routing Single-Rail Format (Binary Data
Stream) data to the Receive Terminal Equipment
a. Operating in the HOST Mode
Configure Channel(n) to output Single-Rail data to
the Terminal Equipment by writing a "1" into the SR/
(DR)_(n) bit-field of Command Register CR3-(n).
The configured channel outputs Single-Rail data to
the Receiving Terminal Equipment via its correspond-
ing RPOS(n) and RxClk(n) output pins as illustrated
in Figure 25 and Figure 26.
b. Operating in the Hardware Mode
Configure the XRT7302 to output Single-Rail data
from the Receive Sections of all channels by pulling
the SR/(DR) pin to VDD.
N
OTE
:
When the XRT7302 is operating in the Hardware
Mode, the setting of the SR/(DR) input pin applies globally
to both channels.
