GND

Description

Auxiliary VCC: This pin is connected to the

system’s 3.3/5V power supply. For the device

to 5V tolerant, connect to +5V power.

CORE_VCC: This pin provides power to the

core circuitry of the OZ6812. It must be

connected to a 3.3V power supply.

PCI Bus VCC: These pins can be connected to

either a 3.3V or5V power supply. The PCI bus

interface will operate at the voltage applied to

these pins, independent of the voltage applied

to other OZ6812 pin groups.
