Judging from the number of responses (0) I got to my question about EMI problems from compactPCI backplanes I am assumiong that either no one uses cPCI backplanes or I'm the only one that has experienced problems when testing in this environment. I didn't think that ever happened in this group. I'll repost this just in case some of you didn't get the last one.
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? Please feel free to respond privately if the question is unclear. I wasn't sure if it was worded properly.
