Transmit STS-3/STM-1 Data
Output - Redundant Port:
This output pin, along with TXLDATO_R_P functions as the
Transmit
transmission to remote terminal equipment) or to the system
back-plane (for transmission to some other System board)
For “High-Speed” Back-Plane Applications, the user should note
that data is output from these output pins upon the rising/falling
edge of “TXLCLKO_R_P/TXLCLKO_R_N”).
Note:
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
Applications. 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:
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
Applications. 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:
