1. The range that deskew is possible in the input data

Please refer to the setup timing requirement in the DPHY440 as shown below,

2.Edge position range of output data after deskew

The re-timed version is centered within the DBCP/N clock.

Thanks

Hi David-san

Thank you for answering.

1. The range that deskew is possible in the input data

Please refer to the setup timing requirement in the DPHY440 as shown below,

-> I understood.

2.Edge position range of output data after deskew

The re-timed version is centered within the DBCP/N clock.

-> How much variation is there from the center?
Is it correct to understand that it is not up to ±0.1UI?

Best regards,

Higa
