hello all I am working on a new project which includes a PCI bus. I am not familier with this bus and I will appriciate to get any material or links about SI issues in PCI bus design. I dont understand the voltage supply to the bus. If i have a 3.3V key it means that the card works with only 3.3V so why to supply 5v to the board?
