Honored Contributorhow tooutput a high speed clock
I need a clock to control high speed AD.But I measure it with oscillograph finding it is very bad so that AD can't work. thank you very much

Honored ContributorIf I can't get high performance clock from FPGA,what should I do? I need change the ADC clock to control sampling rate(we are designing a digital storage osciioscope). I just need a 1M time Sampling clock and 200M Equivalent Sampling,so I need a clock from FPGA. I just change the ADC clock's frenquency to get different sampling rate.I don't know why FPGA output signal(a little high frenquency) is so bad.
