I am considering ADS5407 in an application where the clock frequency will be constantly changing up and down in the range 40 MHz to 500 MHz. From the data sheet it is not clear how this ADC behaves when presented with a non-stationary clock.
Are there limits to how quickly the clock frequency may change? Is it sufficient to adhere to the 40-60% duty cycle requirement while the frequency ramps up and down to get good behavior?
