9 years agoAll three ADC chips must be driven by the same source clock, so the DCO of the one you use has a 0PPM difference from the other chips. From your description, there is no difference between the three ADCs, so there's no reason I could say one is better, but no, I assume they're laid out similar and it wouldn't matter.
I assume DCO is the clock, what's the FCO? I'm not sure without knowing it's functionality.
