Hi Rodrigo Natal,
Thank you very much for your kindly reply. I have a few other questions as below.
1. The retimer does not terminate the FEC even the CDR disabled?
2. if the CDR is disabled, how much output jitter will increase?
3. Could you please to help confirming the serdes rate and design as the attachment can be supported? The upstream data should be send to two switch at same time.
Thanks a lot.
