Hello,

Below is eye diagram of DS80PCI800. The eye mask looks not in the center as below. if remove re-driver, the eye mask will be in the center. Does it have any problem for this phenomenon ? Thank you.

Hi Patrick,

Can the settings on the PCI800 be changed to improve the eye mask location? Maybe reducing the DS80PCI800 de-emphasis slightly could help?

Regards,

Lee

Hello Lee

The de-emphasis are low level will be slightly shift condition. But increase, the eye mask location will be shift large. Thank you.
