DAC37J84: Details of CDR algorithm

Hi Team,

My customer wants to know the details of the clock/data recovery algorithm
which described in the function of config61 bit2:0 of the datasheet page.83.
It seems that the details are not described in the datasheet.

Because the state of LINK changes according to the CDR algorithm setting
on the customer's board.

If you have details of the CDR algorithm, I would like to get them.

Best regards,
