Digital Ground. Ground for digital I/O circuits
and control logic.
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.
Ground for the PLL.
Regulated DC Power Supply Input to the VCO
voltage regulator. Must be connected to
VCCIF (pin 29) via decoupling network.
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.
DC ground for VCO and LO circuits.
Ground for exposed die paddle.
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).

Signal ground for the receive mixers.
Signal ground for the transmitter.
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.
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.
DC ground to IF circuits.
Bandgap decouple voltage. Decoupled to
ground with a capacitor.
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.
