Honored ContributorFFT Frequency Range
I am using the 50MHz internal clock of the Stratix III to collect samples of a chirp signal operating at 30kHz to 80kHz. I read in one of the forums that the FFT MegaCore output frequencies are 0~Fs...

Honored ContributorNormally ADCs require clean clock signal for sampling but since you are dealing with KHz you may try generate clock from fpga logic (divide using counter) and apply it to both ADC and FFT. It will have jitter but your application may tolerate it.
