Frequency Deviation = 58 × (9.8304 MHz)/2
Not production tested; based on characterization.
The output power can be varied in both ASK/FSK mode by altering the relevant external resistor.
Measured using spectrum analyzer, 1 MHz span, 100 kHz RBW, maximum hold enabled.
Maximum power-down current specification applies for the OSC2 pin grounded.
Measured >461.9 kHz away from channel.
Maximum recommended crystal ESR. The crystal oscillator works with crystals with higher ESR, but this results in longer power-up times.
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.
