Transmit Clock Input for TPData and TNData - Channel (n):
This input pin must be driven at 34.368 MHz (for E3 applications),
44.736 MHz (for DS3 applications), or 51.84 MHz (for SONET STS-1
applications). The XRT73L04B uses this signal to sample the
TPData_(n) and TNData_(n) input pins. By default, the XRT73L04B is
configured to sample these two pins on the falling edge of this signal.
N
OTE
:
If the XRT73L04B is operating in the HOST Mode, then the
device can be configured to sample the TPData_(n) and TNData_(n)
input pins on either the rising or falling edge of TxClk_(n).

I
Transmit Positive Data Input - Channel (n)
:
The XRT73L04B samples this pin on the falling edge of TxClk_(n). If the
device samples a "1", then it generates and transmits a positive polarity
pulse to the line.
The data should be applied to this input pin if the Transmit Section is
configured to accept Single-Rail data from the Terminal Equipment.
N
OTE
:
If the XRT73L04B is operating in the HOST Mode, then the
XRT73L04B can be configured to sample the TPData_(n) pin on either
the rising or falling edge of TxClk_(n).

Transmit Negative Data Input - Channel (n):
The XRT73L04B samples this pin on the falling edge of TxClk_(n). If the
device samples a "1", then it generates and transmits a negative polarity
pulse to the line.
In Single-Rail Mode, this pin must be tied to GND to enable the HDB3/
B3ZS Encoder and Decoder, (internally pulled-down).
In Dual-Rail Mode this input is the N-Rail Data input.
N
OTE
:
If the XRT73L04B is operating in the HOST Mode, then the
XRT73L04B can be configured to sample the TNData_(n) pin on either
the rising or falling edge of TxClk_(n).
