Power Sequencing
Startup sequencing of the power supply voltages is not required. However, a power-down cycle must complete

Analog Voltage Filter
The analog voltages used for the on-chip PLLs can be derived from the logic voltage, but must be filtered before entering the
PPC440EP. A Separate filter, as shown below, is recommended for each voltage.
