The manner that the LIU handles Dual-Rail data is
described below and illustrated in Figure 8. The
Transmit Section of a Channel typically samples the
data on the TPData and TNData input pins on the fall-
ing edge of TxClk_(n).
TxClk_(n) is the clock signal that is of the selected
data rate frequency for E3 = 34.368 MHz, DS3 =
44.736 MHz and STS-1 = 51.84 MHz. If the Transmit
Section samples a “1" on the TPData input pin, the
Transmit Section of the XRT73L02 generates a posi-
tive polarity pulse via the TTIP_(n) and TRing_(n)
output pins across a 1:1 transformer. If the Transmit
Section samples a "1" on the TNData input pin, then
the Transmit Section ultimately generates a negative
polarity pulse via the TTIP_(n) and TRing_(n) output
pins across a 1:1 transformer.
2.1.2
Configure Channel (n) to accept Single-
Rail Data from the Terminal Equipment
To transmit data in a Single-Rail data from the Termi-
nal Equipment, configure the XRT73L02 in the HOST
Mode.
Write a "1" into the TxBin_(n) (TRANSMIT BINary)
bit-field of Command Register CR1-(n) shown below.

:
Please refer to Table 2 for the Address of the individ-
ual Channel (n).
The Transmit Section of each channel samples this
input pin on the falling edge of the TxClk_(n) clock
signal and encodes this data into the appropriate bi-
polar line signal across the TTIP_(n) and TRing_(n)
output pins.
