Receive Serial Data Input. Receive Serial data arrives on the rising edge
of the clock. Note: Unused timeslots on this pin must be filled with all
1s.
Serial Interface Receive Clock Input. Reference clock for receive serial
data on RSERI. Gapped clocking is supported, up to the maximum RCLKI
frequency of 52MHz.
Receive Data Enable Port n. An 8kHz synchronization pulse, used to
denote the first Channel 1 of the 8.192Mbps byte-interleaved IBO data
stream. Note that this input is also used to generate the receive byte
synchronization if X.86 mode is enabled.
Receive Clock Output from the LIU on Transceivers 1–4. Buffered
recovered clock from the network. Previously named RDCLKO1-4. Not
used for most DS33R41 applications.
Receive Negative Data from the LIU on Transceivers 1–4. Updated on
the rising edge of RCLKOn with the bipolar data out of the line interface.
Not used for most DS33R41 applications.
Receive Positive Data from the LIU on Transceivers 1–4. Updated on
the rising edge of RCLKOn with bipolar data out of the line interface. Not
used for most DS33R41 applications.
Transmit Clock Output from the Framer on Transceivers 1–4.
Buffered clock that is used to clock data through the transmit-side
formatter (either TCLKT or RCLKI). Not used for most DS33R41
applications.
Transmit Negative-Data Output from Framer on Transceivers 1–4.
Updated on the rising edge of TCLKO with the bipolar data out of the
transmit-side formatter. Not used for most DS33R41 applications.
Transmit Positive-Data Output from Framer on Transceivers 1–4.
Updated on the rising edge of TCLKO with the bipolar data out of the
transmit-side formatter. Can be programmed to source NRZ data via the
output-data format (TR.IOCR1.0)-control bit. Not used for most DS33R41
applications.
