Operating temperature range is as follows: 0°C to +50°C.
Frequency Deviation = 34 × (9.8304 MHz )/2

. Error in the crystal will be reflected in variation in the desired deviation.
3
Not production tested. Based on characterization.
4
The output power can be varied in both ASK/FSK mode by altering the relevant external resistor.
5
Measured using Spectrum Analyzer, 1 MHz span, 100 kHz RBW, MAX HOLD enabled.
6
Maximum power-down current spec applies for the OSC2 pin grounded.
7
Measured > 461.9 kHz away from channel.
8
This spec refers to the time taken for the PLL to regain lock after the PA has been enabled. The PA is should only be enabled after the PLL has settled to the correct
frequency.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
This device is a high performance RF integrated circuit with an ESD rating of
<1 kV and it is ESD sensitive. Proper precautions should be taken for
handling and assembly.

GND = RFGND = DGND = 0 V.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
