When the transceiver block becomes LTR (Lock to Reference) or LTD (Lock to Data) by CDR (Clock Data Recovery), do I need to put a reset?

If there is a switch between LTR / LTD, we recommend that you reset it once.

There are various reset sequences depending on the configuration of the transceiver.

Search for the keyword "Transceiver Reset Sequences Chart" from the Device Handbook at the URL link below, and select the appropriate reset control from the chart in Figure 4-2.
