    Hello,
    some points for your reference:
    1. pls identify and check where the RE over spec. in your system, it is from the FPDLink channel with serializer or from the LVDS channel with panel? it is important for you to stop the noise source.
    2. the FPD-Link high speed trace, the collateral grounding is not good enough, you should keep the continuing grounding close to the high speed trace.
    3. for CMC, pls check the spec.
    4. based on the 1st debug, you can focus in FPD-Link or LVDS channel or the panel side.


    regards,
    Steven
