Transmit STS-12/STM-4 Data - Negative Polarity PECL Output -
Redundant Port:
This output pin, along with TXL_DATA_R_P functions as the Trans-
mit Data Output, to the System back-plane (for transmission to
some other System Board) or an Optical Transceiver (for transmis-
sion to remote terminal equipment).
For High-Speed Back-Plane Applications, it should noted that data
is output from these output pins upon the rising/falling edge of
TXL_CLKO_R_P/TXL_CLKO_R_N).

Transmit STS-12/STM-4 Clock - Positive Polarity PECL Output:
This output pin, along with TXL_CLKO_N functions as the Transmit
Clock Output signal. These output pins are typically used in High-
Speed Back-Plane Applications. In this case, outbound STS-12/
STM-4 data is output via the TXL_DATA_P/TXL_DATA_N output
pins upon the rising edge of this clock signal.
