Signal Description

VDD

VDDA

Power—These pins provide power to the internal structures of the chip, and should

all be attached to VDD.

Analog Power—This pin is a dedicated power pin for the analog portion of the chip

and should be connected to a low noise 3.3V supply.

VSS

VSSA

TCS

GND—These pins provide grounding for the internal structures of the chip, and should

all be attached to VSS.

Analog Ground—This pin supplies an analog ground.

TCS—This Schmitt pin is reserved for factory use and must be tied to VSS for normal

use. In block diagrams, this pin is considered an additional VSS.
