Hello TI,
On page 4 of the ADS42JB69 datasheet, the chip gets 12.1 ENOB at 2.5 Vpp full scale, and the SNR improves from 74.7 dBFS at 170 MHz to 75.6 dBFS at 70 MHz. If I have a broadband signal from 0 to 125 MHz, is it possible to filter out the frequencies above the Nyquist bandwidth (i.e. 125 to 900 MHz, as the highest sampling rate is 250 MSps) to improve this value? If not, then if I have a 0 to 125 MHz band limited signal at the input, will chip yield at least 74.7 dBFS SNR?
