Archive of the former Yahoo!Groups mailing list: MOTM

Question for Paul, mostly, but maybe others have considered the same thing:
If I'm building a module from scratch, and I want it to play nicely with my
MOTM modules (present and future), and it's drawing all three voltages
through a MOTM-standard 6-pin power connector, and it's a hybrid
analog/digital module, how do I connect together the digital ground and the
analog ground on my PC board? It may be something of a moot point because
AFAICT my Power-One triple supply has the grounds connected together anyway,
but I'm wondering whether there is some little nicety that I should observe,
like maybe using a ferrite bead instead of just plain copper.

Thanks for any opinions or suggestions.
