Hi all, Some people are saying that PCI Vih =3D 0.9*Vcc but im my opinion this = is the driver output DC specification. I've found out following values from the PCI specification and I believe = these are the correct ones. +5V I/O mode PCI -> Vih min. =3D +2.0V +3.3V I/O mode PCI -> Vih min. =3D 0.5 * Vcc Which information source should I believe?
