Description
Regulator Voltage for RF. A 220 nF capacitor should be placed between this pin and ground for
regulator stability and noise rejection.
External Bias Resistor. A 36 kΩ resistor with 2% tolerance should be used.
Regulator Voltage for RF. A 220 nF capacitor should be placed between this pin and ground for
regulator stability and noise rejection.
LNA Positive Input in Receive Mode. PA positive output in transmit mode with differential PA.
LNA Negative Input in Receive Mode. PA negative output in transmit mode with differential PA.
Single-Ended PA Output.
Power Supply Pin Two. Decoupling capacitors to the ground plane should be placed as close as
possible to this pin.
No Connect.
Regulator Voltage for the VCO. A 220 nF capacitor should be placed between this pin and ground for
regulator stability and noise rejection.
Guard/Screen for VCO. This pin should be connected to Pin 9.
Regulator Voltage for the Synthesizer. A 220 nF capacitor should be placed between this pin and
ground for regulator stability and noise rejection.
External Capacitor for Wake-Up Control. A 150 nF capacitor should be placed between this pin and
ground.
The 26 MHz reference crystal should be connected between this pin and XOSC26N.
The 26 MHz reference crystal should be connected between this pin and XOSC26P.
Internal Guard/Screen for the Digital Circuitry. A 220 nF capacitor should be placed between this pin
and ground.
Regulator Voltage for Digital Section of the Chip. A 220 nF capacitor should be placed between this
pin and ground for regulator stability and noise rejection. This can be achieved by shorting it to
Pin 15 and sharing the capacitor to ground.
Digital GPIO Pin 0.
Digital GPIO Pin 1.
Digital GPIO Pin 2.
Interrupt Request, Digital GPIO Test Pin 3. An RC filter should be placed between this pin and the
host processor. Recommended values are R = 1.1 kΩ and C = 1.5 nF.
