Would you pls help to check how to handle unused RX&TX pin of retimer? Thanks a lot!
Is it ok for below terminated circuit?
The user may either leave these unused high-speed pins floating or terminate them to GND. Note that TI supports the implementation of a retimer channel full power down register write routine. When this channel power down is applied, the hardware configuration of unused pins is even less critical.

In reply to Rodrigo Natal:
Thanks a lot.
If I terminate them to GND, what value of resister is recommended? Is there a document describing that? If yes, would you pls send it to me? Thanks a lot!
In reply to Zhizhao Niu:
Please use 49.9-ohm Resistor from each pin to GND.
