Reverse Serial Pre-CDR Loopback
The reverse serial pre-CDR loopback mode uses the analog portion of the
transceiver. An external source (pattern generator or transceiver)
generates the source data. The high-speed serial source data arrives at the
high-speed differential receiver input buffer, loops back before the CRU
unit, and is transmitted though the high-speed differential transmitter
output buffer. It is for test or verification use only to verify the signal
being received after the gain and equalization improvements of the input
buffer. The signal at the output is not exactly what is received since the
signal goes through the output buffer and the VOD is changed to the
VOD setting level. The pre-emphasis settings have no effect.
