Transmit STS-3/STM-1 Clock - Positive Polarity PECL Output:
This output pin, along with TXLCLKO_N functions as the Transmit Clock
Output signal.
These output pins are typically used in High-Speed Back-Plane Applica-
tions. In this case, outbound STS-3/STM-1 data is output via the
TXLDATO_P/TXLDATO_N output pins upon the rising edge of this clock
signal.
NOTE: For APS (Automatic Protection Switching) purposes, this output
pin, along with TXLCLKO_N functions as the Primary Transmit
Output Clock signal.

Transmit STS-3/STM-1 Clock - Negative Polarity PECL Output:
This output pin, along with TXLCLKO_P functions as the Transmit Clock
Output signal.
These output pins are typically used in High-Speed Back-Plane Applica-
tions. In this case, outbound STS-3/STM-1 data is output via the
TXLDATO_P/TXLDATO_N output pins upon the falling edge of this clock
signal.
NOTE: For APS (Automatic Protection Switching) purposes, this output
pin, along with TXLCLKO_N functions as the Primary Transmit
Output Clock signal.

tions. In this case, outbound STS-3/STM-1 data is output via the
TXLDATO_R_P/TXLDATO_R_N output pins upon the rising edge of this
clock signal.
NOTE: For APS (Automatic Protection Switching) purposes, this output
pin, along with TXLCLKO_R_N functions as the Redundant
Transmit Output Clock signal.

Redundant Port:
This output pin, along with TXLCLKO_R_P functions as the Transmit
Clock Output signal. These output pins are typically used in High-Speed
Back-Plane Applications. In this case, outbound STS-3/STM-1 data is
output via the TXLDATO_R_P/TXLDATO_R_N output pins upon the ris-
ing edge of this clock signal.
