Power Supply Inputs.
Each of these pins must be connected to a common
+3.3 VDC power supply. A de-coupling capacitor to digital ground should be
supplied for every one of these pins.

VCCR
-
Analog Supply Inputs - Receive.
Each of these pins must be connected to a
common +3.3 VDC power supply. A de-coupling capacitor to GND should be
supplied for every one of these pins. Use ferrite beads to create a separate
analog VCC plane.
