FUNCTION

DIAGRAM

POWER & GROUND

VSS

GND

Digital Ground. Ground for digital I/O circuits

and control logic.

N/A

VCCPLL

PWR/O

(Decouple

only)

PLL Supply. DC power supply decoupling

point. This pin is connected to the output of

the regulator and to the PLL supplies. A

capacitor must be tied between this pin and

ground to decouple (bypass) noise and to

stabilize the regulator.

See Pin 11 below.

GNDPLL

GND

Ground for the PLL.

N/A

VCCB

PWR/I

(Regulated

Input)

Regulated DC Power Supply Input to the VCO

voltage regulator. Must be connected to

VCCIF (pin 29) via decoupling network.

N/A

VCCVCO

PWR/O

(Decouple

only)

DC power supply decoupling point for the

VCO. Connected to the output of the VCO

regulator. A capacitor must be tied between

this pin and ground to decouple (bypass)

noise and to stabilize the regulator.

N/A

GNDLO

GND

DC ground for VCO and LO circuits.

N/A

GNDDB

GND

Ground for exposed die paddle.

See Pin 20 below

VCCRXMIX

PWR/I

(Regulated

Input)

Regulated RX mixer DC supply input. A

capacitor must be tied between this pin and

ground to decouple (bypass) noise. Must be

connected to VCCTXMIX (pin 27).

N/A

VCCLNA

PWR/I

(Regulated

Input)

Regulated DC Power supply input to the LNA.

A capacitor must be tied between this pin and

ground to decouple (bypass) noise. Must be

connected to VCCTXMIX (pin 27).

N/A

GNDMIX

GND

Signal ground for the receive mixers.

N/A

GNDTX

GND

Signal ground for the transmitter.

N/A

VCCRF

PWR/O

(Decouple

only)

DC power supply decoupling point for the LO

chain. Connected to the output of a regulator.

A capacitor must be tied between this pin and

ground to decouple (bypass) noise and to

stabilize the regulator.

N/A

VCCA

PWR/I

(Unregulated

Input)

Unregulated DC power supply input to voltage

regulators and unregulated loads: 2.7 to 3.6V.

VCCA is the main (or master) analog VCC pin.

There must be capacitors to ground from this

pin to decouple (bypass) supply noise.

N/A

GNDIF

GND

DC ground to IF circuits.

N/A

VBG

PWR/O

(Decouple

only)

Bandgap decouple voltage. Decoupled to

ground with a capacitor.

N/A

VCCTXMIX

PWR/O

(Regulated

Output)

DC power supply output and decoupling point

for TX mixer regulator. A capacitor must be

tied between this pin and ground to decouple

(bypass) noise and to stabilize the regulator.
