System Supply (V)

Figure 3-3:Relationship For 3.3V Input Buffer Compliance

Figure 3-3shows the small range of supply voltage values where VIL or VIH are technically non-compliant. Note that this may occur with any PCI device if the input buffer supply voltage is different from the supply voltage of the driving device. For best results, use a high precision voltage regulator to generate VCCINT.

For 3.3 volt signaling in Virtex-II Pro, Virtex-4, Spartan-3, and Spartan-3E devices, the VCCO supply must be reduced to 3.0 volts and derived from a precision regulator. This reduction of the output driver supply provides robust device protection without sacrificing PCI electrical compliance, even in the extreme case where the 3.3 volt system supply climbs as high as 3.6 volts as allowed by the PCI Local Bus Specification.
