O
Transmit TTIP Output - Channel (n):
The XRT73LC03A uses this pin along with TRing_(n) to transmit a bipo-
lar line signal via a 1:1 transformer.

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 XRT73LC03A uses this signal to sample the TPData_(n) and
TNData_(n) input pins. By default, the XRT73LC03A is configured to
sample these two pins on the falling edge of this signal.
NOTE: If the XRT73LC03A 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 XRT73LC03A 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.
NOTE: If the XRT73LC03A is operating in the HOST Mode, then the
XRT73LC03A can be configured to sample the TPData_(n) pin on either
the rising or falling edge of TxClk_(n).

I
Transmit Negative Data Input - Channel (n):
The XRT73LC03A 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.
NOTE: If the XRT73LC03A is operating in the HOST Mode, then the
XRT73LC03A can be configured to sample the TNData_(n) pin on either
the rising or falling edge of TxClk_(n).
