Hi z0806020433,

Hi z0806020433,

The one selection sets as clock the internal clock of the ADC and the other selection chooses as clock of the ADC the system clock. Go with the 0 option (internal high-speed adc clock) since that is recommended by Dialog, the internal ADC clock is approximatelly 200MHz.
