  • Hi user3555671

    Can you provide examples of the good data from the three chips that are OK and the bad data from the one that has the issue?

    Please also send us the schematics for your board including input signal path components and data path to FPGA.

    I will delete your two other identical postings.

    Best regards,

    Jim B
