2.3.2 Implementation Example

It is recommended to separate the power inputs of the internal oscillators and PLL circuits (VDDOSC, VDDAUDIOPLL and VDDPLLA) using a series 10 µH inductors on each input. Other peripheral power inputs (VDDIOP0, VDDIOP1, VDDISC etc.) may use series 180Ω ferrite beads instead when necessary, but the preferred choice is to connect those belonging to the same voltage in a single, solid, unsplit power plane..
