Function
Oscillator Pin. For use with crystal reference only. This is three-stated when an external reference oscilla-
tor is used.
Voltage Controlled Oscillator Ground.
Input to the RF Fractional-N Divider. This pin allows the user to connect an external VCO to the part.
Disabling the internal VCO activates this pin. If the internal VCO is used, this pin should be grounded.
Positive Supply for the Digital Circuitry. This must be between 2.3 V and 3.6 V. Decoupling capacitors
to the analog ground plane should be placed as close as possible to this pin.
Ground for Output Stage of Transmitter.
The modulated signal is available at this pin. Output power levels are from –16 dBm to +12 dBm. The
output should be impedance matched to the desired load using suitable components. See the RF Output
Stage section.
Ground Pin for the RF Analog Circuitry.
The tuning voltage on this pin determines the output frequency of the Voltage Controlled Oscillator
(VCO). The higher the tuning voltage, the higher the output frequency.
A 0.22 µF capacitor should be added to reduce noise on VCO bias lines. Tied to the C
A 2.2 µF capacitor should be added at C
stability. A reduced capacitor will improve regulator power-on time but may cause higher spurious
components.
