    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.


    Regards,

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?
