1. The analog voltages can be derived from the +1.2V and +2.5V supplies, but must be filtered as shown below before entering
the PPC405EX. Use a separate filter for each voltage. This circuit can be used for AVDD, AHVDD , SAVDD, and EAVDD. Use
AGND with AVDD and AHVDD. Use SAGND with SAVDD. Use EAGND with EAVDD. These analog grounds must be brought
out and connected to the digital ground plane at the filter capacitor. Keep all wire lengths as short as possible.
