Forum Post: RE: ADS4226EVM issue

Hi,

The sampling clock to ADS42xxEVM is usually provided by external signal generator for the flexibility of sampling frequency, and the circuitry of input clock is shown as below. ADS42xxEVM GUI is based on configuring only ADS42xx device itself. It'll be best if you can use signal generator for sampling clock, then you don't have to mount VCXO onboard.

Thanks,

KW
