Notes:

1. GVDD, OVDD, AVDD, and VDD must track each other and must vary in the same direction—either in the positive or negative

direction.

2. AVDD is the input to the filter discussed in Section 25.1, “PLL Power Supply Filtering,” and is not necessarily the voltage at

the AVDD pin.

2. Note that with the PCI overshoot allowed (as specified above), the device does

not fully comply with the maximum AC ratings and device protection guideline outlined in

the

PCI Rev. 2.3 Specification (Section 4.2.2.3).
