Hi All,

This is a question regarding systems which use CompactPCI bus architecture.
On a cPCI backplane the PCI clock is routed to every slot on the backplane
with up to 7 peripheral slots possible on a normal backplane. My question is
this: With the cPCI specification calling out specific trace lengths for
clock traces on both the backplane itself and on peripheral cards, have
other people experienced any unique EMI problems in trying to meet the
design constraints associated with this synchronous bus; especially where
there are unpopulated slots on the backplane?

Thanks in advance,

Bill Fleury
