DS250DF230: An issue has occurred where the CDR Lock is not engaging.

Part Number: DS250DF230

Tool/software:

I am using the DS250DF230 25-Gbps Multi-Rate 2-Channel Retimer, but I am experiencing an issue where the CDR Lock does not engage when providing a 25MHz clock.

Upon searching for similar inquiries on E2E, I found that there seems to be a separate programming guide document available. Could you provide me with this document as well?

I have also attached the schematic of our design for reference.

ps, I would like to ask if it is possible to share the EVB (Evaluation Board) schematic as well.
