Validating performance of ADCs and DACs is hard enough for the converter and board vendors. We have those challenges, as well as system level concerns. When you place an converter a few cm from a 100W GPU, how would you think the
SFDR would change? Fun stuff.

What a cute couple. Is the one on the right one of your offspring? How well do they play together? Multiple ground planes? mu-metal? Differential busses?
They are good friends. Our 1~3 GHz "RF" are our client's IF; which means that (almost) everything is SE 50 ohm transmission line. AC coupling by cap or xfmr goes a long way to keep things quiet. Needless to say the digital bits stay in their own world. -S
