AUX_VCC
This pin is connected to the system
’
s 5-
volt power supply. In systems where 5
volts is not available, this pin can be
connected to the system
’
s 3.3-volt supply
if your PCI_VCC and CORE_VCC
connected to 3.3V
This pin provides power to the core
circuitry of the OZ6833. It could be
connected to a 3.3 power supply.
All OZ6833 ground pins should be
connected to system ground.
