I have a customer experiencing this problem with the JESD204B IP:

Has this kind of problem been reported before? Do you have any idea what might be causing this problem or what I should look at to try and track down the problem? Regards, Steve Zack

Hie,

If you are observing disparity error and observing an unusable eye pattern( I am assuming a closed eye or eye diagram cannot be detected by scope of ADC), this could suggest your signal degradation due to channel loss. You could try turning up the Equalization settings within the Arria 10 transceivers to check if can compensate for the board/cable channel loss.
