[SI-LIST] On choosing center tap capacitor value for differential termination

Hi,

I am trying to find some guidelines concerning choosing the 
capacitor that is the center tap of two series resistors that form a 
differential termination. If my information is correct, the 
combination either of the resistors and the center tap capacitor, 
forms an AC common mode termination. 

Is there a difference between choosing a center tap capacitor used 
in this way and choosing a capacitor for an AC termination?

This inquiry is directed towards the reduction of radiated 
emissions. The signals in questions have a rise time of about a 
nanosecond.

Thank You
Tom Cipollone
