Receive Overhead Data Interface – Framing Pulse
indicator
This output pin functions as the “Receive Overhead Clock”
output for the receive system side interface when the
XRT94L33 is configured to operate in DS3/E3 mode, however,
it functions as the “Receive STS-1 Overhead Clock” output
when the device is configured to operate in the STS-1 mode.
When configured to operate in DS3/E3 mode:
This output pin pulses “high” whenever the Receive Overhead
Data Output Interface block outputs the first overhead bit of a
new DS3 or E3 frame.
When configured to operate in STS-1 mode:
These output pins, along with “RxOH_n”, “RxOHEnable_n”
and “RxOHClk_n” function as the “Receive STS-1 TOH and
POH Output Port”.
These output pins will pulse “high” coincident with either of the
following events.
When the very first TOH byte (A1), of a given STS-1 frame, is
being output via the corresponding “RxOH_n” output pin.
When the very first POH byte (J1), of a given STS-1 frame, is
being output via the corresponding “RxOH_n” output pin.
The external circuitry can determine whether these output pins
are pulsing high for the first TOH or POH byte by checking the
state of the corresponding “RxOHEnable_n” output pin.
For mapper applications, Please let this pin “float”.
