VCC
-
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.

-
Analog Supply Inputs - Transmit.
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.
1. I = Input, O = Output, I/O = Input/Output, D = Digital, A = Analog, AI = Analog Input,
A I/O = Analog Input/Output, OD = Open Drain, OS = Open Source, PD = Pull Down, PU = Pull Up.
NC = No Clamp. Pad does not clamp input in the absence of power.
2. Pins are 5V tolerant, unless indicated.
