Hallo, I connected hmcad1511 to FPGA,it make spectrum analyser. patterns looks good. 500MSPS dual channel mode. But in spectrum is 3 spurs at 125, 187.5, 62.5 Mhz with 20 dB up of noise floor ( noise -85 dB). fclk possible do this spurs. I trying tune adc registers ( LVDS loads and currents) no helps. Is way to delete spurs from spectrum ? Thank you
