LVPECL
Receive STS-12/STM-4 Clock - Positive Polarity PECL Input -
Redundant Port:
This input pin, along with RXL_CLKL_R_N functions as the Recov-
ered Clock Input, from a System back-plane or an Optical Trans-
ceiver. The Receive STS-12/STM-4 Interface Block will sample the
data, applied at the RXLDATA_P/RXLDATA_N input pins, upon the
rising edge of this signal.
NOTE: For APS (Automatic Protection Switching) purposes, this
input pin, along with RXL_CLKL_R_N functions as the
Redundant Receive Clock Input Port.

LVPECL
Receive STS-12/STM-4 Clock - Negative Polarity PECL Input -
Redundant Port:
This input pin, along with RXL_CLKL_P functions as the Recov-
ered Clock Input, from a System back-plane or an Optical Trans-
ceiver. The Receiver STS-12/STM-4 Interface Block will sample
the data applied at the RXLDATA_P/RXLDATA_N input pins, upon
the falling edge of this signal.
NOTE: For APS (Automatic Protection Switching) purposes, this
input pin, along with RXL_CLKL_R_ P functions as the
Redundant Receive Clock Input Port.

RXL_DATA_P
I
LVPECL
Receive STS-12/STM-4 Data - Positive Polarity PECL Input:
This input pin, along with RXL_DATA_N functions as the Recov-
ered Data Input, from a System back-plane or an Optical Trans-
ceiver. The Receive STS-12/STM-4 Interface block will sample the
data applied to these input pins, upon the rising edge of the
RXL_CLKL_P (and the falling edge of the RXL_CLKL_N) signals.
NOTE: For APS (Automatic Protection Switching) purposes, this
input pin, along with RXL_DATA_N functions as the
Primary Receive Data Input Port.
