ADC32RF45: ADC32RF45

Amnon Aliphas

Part Number: ADC32RF45

I am having a problem in that the spectra of all my sampled signals with the ADC32RF45 exhibits spurs. There are spikes created by DC offset errors at fs/2 and fs/4. I suspect that the other spurs are created by the gain mismatch of the interleaved branches.. 

Is there any suggestion as to a calibration procedure to compensate for the gain difference in each branch?
