Transmit Reference Clock – Negative Polarity PECL Input:
This input pin, along with “REFCLK_P” and “REFTTL” can be
configured to function as the timing source for the STS-3/STM-1
Transmit Interface Block.
If the user configures these two input pins to function as the
timing source, then the user must apply a 155.52MHz clock
signal, in the form of a PECL signal to these input pins. The user
can configure these two inputs to function as the timing source
by writing the appropriate data into the “Transmit Line Interface
Control Register “ (Address Location = 0x0383)
Note:
Transmit STS-3/STM-1 Data
Output:
This output pin, along with TXLDATO_N functions as the
Transmit Data Output, to the Optical Transceiver or to the
system back-plane.
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_P/TXLCLKO_N”.
Note:
Transmit STS-3/STM-1 Data – Negative Polarity PECL
Output:
This output pin, along with TXLDATO_P functions as the
Transmit Data Output, to the Optical Transceiver or to the
system back-plane.
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_P/TXLCLKO_N.
Note:
Transmit STS-3/STM-1 Data - Positive Polarity PECL Output
- Redundant Port:
This output pin, along with TXLDATO_R_N functions as the
Transmit Data Output, to the Optical Transceiver or to the
system back-plane.
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:

Users should set this pin to “0” if “REFTTL” clock input
is used
this output pin, along with “TXLDATO_N” functions as
the “Primary” Transmit STS-3/STM-1 Data Output Port.
this output pin, along with “TXLDATO_P” functions as
the “Primary” Transmit STS-3/STM-1 Data Output Port.
this output pin, along with “TXLDATO_N” functions as
the “Redundant” Transmit STS-3/STM-4 Data Output
Port.
