Output Pin:
These output pins, along with the RxPOHClk_n, RxPOHFrame_n and
RxPOHValid_n function as the Receive SONET POH Processor block -
POH Output port.
These pins serially output the POH data that have been received by each
of the Receive SONET POH Processor blocks (via the incoming STS-12
data-stream). Each bit, within the POH bytes is updated (via these output
pins) upon the falling edge of RxPOHClk_n. As a consequence, external
circuitry receiving this data, should sample this data upon the rising edge
of RxPOHClk_n.
Clock Output Signal:
These output pins, along with RxPOH_n, RxPOHFrame_n and
RxPOHValid_n function as the Receive SONET POH Processor block -
POH Output Port.
These output pins function as the Clock Output signals for the Receive
SONET POH Processor block - POH Output Port. The RxPOH_n,
RxPOHFrame_n and RxPOHValid_n output pins are updated upon the
falling edge of this clock signal. As a consequence, the external circuitry
should sample these signals upon the rising edge of this clock signal.
