PCB Routing Guideline for PCI

[Conor Foley <Conor.Foley@tellabs.com> (by way of Daniel Weaver <dan.weaver@znyx.com>)]

Hi,

We are working on our first PCI design (embedded) and I was wondering
if there are any good tech notes about PCB routing for PCI out there -
things to do/not do, gotchas, requirement for controlled impedance?, max

trace length, etc. The design is only 32bit/33MHz and has no connectors,

so I am not too concerned, however, any suggestion ideas would be
welcome.

Thanks,
Conor.
