Analog power supply, which must be connected to the digital power supply externally. It is
important to provide a decoupling capacitor of 0.1 µF from PLL_VDD to PLL_VSS.
Analog ground. Analog and digital grounds must be connected externally to the same
ground plane.
+3.3 V Digital power supply. This supply handles the 3.3 V external digital I/O devices. It is
important to provide local decoupling capacitors of 0.1 µF to the ground plane on each pin
in addition to a parallel 10 µF capacitor on the ground plane.
+1.8 V Digital power supply. It is important to provide local decoupling capacitors of 0.1 µF
to the ground plane on each pin in addition to a parallel 10 µF capacitor on the ground plane.
Digital ground. Digital and analog grounds must be connected.
+1.8 V linear regulator gate drive output. Generally not used, leave pin float.
