    Hi William,

    Can you ensure that the customer is using the following TMDS PLL settings:

    Register Setting Comment
    0x4D 0x3B ADI Recommended Write
    0x4E 0x6D ADI Recommended Write
    0x4F 0x54 ADI Recommended Write
    0x50 0x90 ADI Recommended Write
    0x53 0x3F ADI Recommended Write
    0x59 0x20 ADI Recommended Write

    These are the latest recommended settings. These settings also apply to the AD9380, AD9381, AD9396, AD9397 and AD9398.

    Thanks,
