. Error in the crystal is 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, maximum hold enabled.
6
Maximum power-down current specification applies for the OSC2 pin grounded.
7
Measured >461.9 kHz away from channel.
8
Maximum recommended crystal ESR. The crystal oscillator works with crystals with higher ESR, but this results in longer power-up times.
9
This specification 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.

This device is a high performance, RF-integrated circuit with an ESD rating
of <1 kV. It is ESD sensitive. Take proper precautions for handling and
assembly.

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.
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
degradation or loss of functionality.
