VDDA

Signal Description

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.

TCS

Signal Description

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.
