Notes:
1. PCI drivers meet PCI specifications.
2. SVREF = SVDD/2
3. The analog voltages used for the on-chip PLLs can be derived from the logic voltage, but must be filtered before entering the
PPC440GR. See “Absolute Maximum Ratings” on page 61.
4. Overshoot and undershoot voltages are for 10% duty cycle.
5. The time for overshoot or undershoot is time above OVDD and the time below 0V.
