    Hi Enhui,

    Please send us the list of register writes the customer is using to config the ADC with.

    Also, is the customer using the ADC3541EVM and what TSW data capture board?

    Or is this their own design? Please advise.

    Thanks,

    Rob

    Hi Rob,

    This is the customer their own design. Below is the list of all register writes:

    For the configuration example, if all the registers need configurate? Or if we have the DDR configurate code example? Thanks

    Hi Enhui,

    Using the EVM and GUI, I was able to generate a config for DDR Bypass mode. The cusotmer will need to program all of these registers in the same order. Below is the capture I took using the attached config to confirm:
