Part Number: ADS5402

Hi,

I would like to know about sampling rate.

My understanding is as below;

- Without interleaving correction, sampling rate of ADS5402 is same with input clock frequency .

- With interleaving correction, sampling rate of ADS5402 is twice input clock frequency .

- Start trigger of sampling is rising edge of input clock.

- When input frequency varies, sampling rate vary in a similar way.

Are these correct?

Best Regards,

Unfortunately all of your assumptions are incorrect. Sampling rate is independent of interleaved correction and input frequency. I would suggest looking through the following PDF to gain more understanding on sample rate as well as other ADC concepts.
