Other Parts Discussed in Thread: ADS5500, , CDCV304, CDCE62002
I am performing 512 point FFT on both adcs with sampling rate 100 MHz
ADS5500 using differential clock source
ADS42LB49 using cmos clock source
The input signal is about 8 MHz.
The FFT noise floor of the power spectra seems lower in ADS5500, I was expecting the ADS42LB49 to perform better?
Does using lvds clock for ADS42LB49 makes a big difference? what other factors could be affecting the performance of ADS42LB49,
I am using ADS42LB49EVAL and a 3rd party board for ads5500.
