JESD204 IP-Core occasionally receives wrong data in internal loopback mode

Hie,

Apologies for the delayed first response. Since you mentioned there is no errors being asserted, this could be a signal tap sampling capture error. However to be certain, could you double check if the 8B10B decode errors are asserted. If yes, then this could be mean the incoming data is corrupted; suggesting intermitently something happens either at the channel level or device level to corrupt the data.

If no, then this could mean the signaltap capture on the Rx side is incorrect. Please check for timing errors related to signaltap path or use a 2xfater sampling clock on signaltap.

Regards,

Nathan
