Notes:

1. PCI-X drivers meet PCI-X 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

PPC440GX. See “Absolute Maximum Ratings” on page 58.

4. During chip power-up, OVDD should begin to ramp before VDD. External voltage should not be applied to the chip I/O pins before

OVDD is applied to the chip. A power-down cycle should complete (OVDD and VDD should both be below 0.4V) before a new power-

up cycle is started.

5. LPDL is least positive down level; MPUL is most positive up level.

6. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board.
