Note: In order to simplify the diagrams, AV_DDI, AV_DDO, and DV_DDIO are shown to be shorted together. In practice,
they may all be separated and connected to different supply domains if desired.
AV_DDO is sensitive to noise and therefore should be filtered through a ferrite bead, with a 10 nF ceramic capacitor
adjacent to each AV_DDO pin. Since this core can take a current in the order of 500 mA, the ferrite bead should be
very low resistance to ensure the drop across it is minimal.
