The serial loopback option is available for all functional modes except PIPE mode. In
this mode, the data from the FPGA fabric passes through the transmitter channel and
looped back to the receiver channel, bypassing the receiver buffer, as shown in
Figure
receiver input buffer is not active in this mode. With this option, you can check the
operation of all enabled PCS and PMA functional blocks in the transmitter and
receiver channels.
The transmitter channel sends the data to both the serial output port and the receiver
channel. The differential output voltage on the serial ports is based on the selected

different clock domains. You must provide an alignment pattern for the word aligner
to enable the receiver channel to retrieve the byte boundary.
Serial loopback mode can only be dynamically enabled or disabled during user mode
by performing a dynamic channel reconfiguration.
