Analog Local Loopback
This loopback feature serializes the 8-bit parallel transmit data
input and presents the data to the transmit serial output and in
addition it also internally routes the serialized data back to the
Clock and Data Recovery block for serial to parallel conversion.
The received serial data input is ignored.

DLOOP Local Loopback
This digital loopback mode interconnects the 8-bit parallel
transmit data input and TXCLK to the 8-bit parallel receive data
output and receive RXCLK respectively while maintaining the
transmit serial data output. If digital loopback is enabled, the
receive serial data input is ignored.
"Low" = Disabled
"High" = Digital Local Loopback Mode Enabled

DLOOP and RLOOPS can be enabled simultaneously
to achieve a dual loopback diagnostic feature in normal
operation.

Transmit Parallel Data Input
Transmit Parallel Clock Output Operation
The 77.76 Mbps (STS-12/STM-4) / 19.44 Mbps (STS-3/STM-1)
8-bit parallel transmit data should be applied to the transmit
parallel bus and simultaneously referenced to the rising edge of
the TXPCLK_IO clock output. The 8-bit parallel interface is mul-
tiplexed into the transmit serial output interface with the MSB
first (TXDI[7:0]).
Alternate Transmit Parallel Clock Input Operation
When operating is this mode, TXPCLK_IO is no longer a paral-
lel clock output reference but reverses direction and serves as
the parallel transmit clock input reference for the PISO (Parallel
Input to Serial Output) block. The 77.76 Mbps (STS-12/STM-4)
/ 19.44 Mbps (STS-3/STM-1) 8-bit parallel transmit data should
be applied to the transmit parallel bus and simultaneously refer-
enced to the rising edge of the TXPCLK_IO clock input.

Transmit Serial Data Output
The transmit serial data stream is generated by multiplexing the
8-bit parallel transmit data input into a 622.08 Mbps STS-12/
STM-4 or 155.52 Mbps STS-3/STM-1 serial data stream.
