Preliminary Data Sheet
Power Sequencing
Startup sequencing of the power supply voltages is not required. However, a power-down cycle must complete
(OVDD and VDD are below +0.4V) before a new power-up cycle is started.
Analog Voltage Filter
The analog voltages (AVdd and EAVdd) used for the on-chip PLLs can be derived from the logic voltage, but must be filtered
before entering the PPC440GRx. A Separate filter, as shown below, is recommended for each voltage.
The filter should keep the analog voltage to analog ground compression/expansion due to noise less than +/-
50 mV.
Keep all wire lengths as short as possible.
Analog grounds must be brought out and connected to the digital ground plane at the filter capacitor.
The impedance of the ferrite bead should be much greater than that of the capacitor at frequencies where noise is
expected.

Notes:
1. Typical power is estimated and is based on a nominal voltage of VDD = +1.5V, TC = 85°C, while running Linux and a test application that
exercises each functiion with representative traffic.
