Hi,
you agree that you are not giving much info about your design?
As a starter question, does your design meet timing? Do you see any warnings, e.g. related to PLL usage?

Hi smile123,

When CDR is in locked to data mode, the status of rx_is_lockedtoref is unknown; it can be high or low or toggling. You do not need to care about rx_is_lockedtoref when rx_is_lockedtodata is high.
