Other Parts Discussed in Thread: ADC3669EVM,

Hi team,

There are differences on analog front end design of ADC3549 in the datasheet of ADC3549 and in the design file of ADC3669EVM. Which one should my customer follow?

    Hi Shunsuke,

    I would use what is shown on the EVM if the customer plans to use the ADC in a wideband application, 1GHz or more is required.

    If not, either of the two datasheet recommendations can be use or implemented.

    Regards,
