DS125DF1610: eye diagram is not in the middle

Part Number: DS125DF1610

Hi expert

Please refer to below for the eye diagram I got from DS125DF1610, I checked several lanes, I found the eye diagram is not in the middle.

1) Is it correct?

2) If something I didn't configure properly, what could be wrong?

Regards

Hi Chris,

This is not a concern, given that the HEO/VEO still have good margins. There is an expected offset while outputting the on-chip eye measurements.

Thank you,

Evan

Thanks, Evan.

So I won't pay attention to this offset anymore, mainly focus on HEO/VEO.

Thanks

Chris
