    Hsiao,
    All FPD-Link(tm) chipsets have been qualified on EMC/EMI test in the 3rd party. To resolve this issue, you should identify the possible clock freq. in your board, such as PCLK freq.? on-board XO? CPU's clocking? etc., also you need check the high speed signal layout, and transmission channels, such as connector, cable shielding performance, etc.

    best regards,
