Reverse serial pre-CDR loopback is available as a subprotocol under custom
configuration. In reverse serial pre-CDR loopback, the data received through the
rx_serial_data port is looped back to the tx_serial_data port before the receiver
CDR. The received data is also available to the FPGA logic.
transceiver channel datapath for reverse serial pre-CDR loopback mode.
The active block of the transmitter channel is only the transmitter buffer. You can
change the V
Manager. The pre-emphasis settings for the transmitter buffer cannot be changed in
this configuration.
