Plesae let me know your advice about below my question.

We verified below about this.

1:We change the register "DLL_PH[4:0] Sample Phase Adjustment, Address 0x6A, [4:0] " from 0x00 to 0x1F.
    But above change does not effect this issue.

2:We change  the register " SYN_SRC[1:0] SSPD Sync Source Selection (CP), Address 0x85, [4:3] " from  0x00 to 0x01.
    But above change does not effect this issue.
