Hello

I have an AD5553 ADC. I don't have any anti-aliasing filter so I need to put an first order RC filter at the input of AD5553.

I've studied below document to design anti-aliasing filter.

But I couldn't calculate the t_acq (acquisition time) for AD5553.

the sampling rate is 65MHz and on the other side I should have the first nyquist zone (DC to 32.5MHz).

How should I calculate the amount of R and C? from above document I got that I should be aware of settling time and other parameters.

Regards
