[SI-LIST]

Thanks to everyone who answered. To summarize what I've learned: 

I understand the idea of linear building blocks and that each element can be 
rearranged and the end result is the same - so in effect the location of the ac 
coupling (dc block) capacitor makes little difference IF ALL THINGS REMAIN THE 
SAME.

As has been pointed out, often ALL THINGS DO NOT REMAIN THE SAME when the 
capacitor is moved around. Different locations allow for different numbers of 
vias which has a great effect on overall SI.

We routinely minimize numbers of vias and try to backdrill vias at connectors 
and other vias where possible on these speed traces.

I have not been subscribed on this forum/freelist long, but I've been a casual 
reader when the topic has been of interest. I appreciate everyone's feedback.
