The customer obtained waveform of CML like attached file below.

cmlout.xlsx

It is not similar with Figure 34 of datasheet.

Do you have a reason why Eye like Figure 34 would not be measured?

Hello,

Can you give me more information on your issue and your system? The more information you give me the quicker I can fix your issue.

Are you 914 and your 913 obtaining LOCK? are the high speed FPD-Link data lanes length matched?

Regards,
Michael W.

na na78-san,

In addition to the comment from Michael, I suggest you to to check whether CMLOUT is enabled.
For me, it looks you don't have any signals out from CMLOUTP/N.

Please make sure 0x3F[4] is set.

Thanks,
Ken
