Notes:

1. All minimum and maximum values are guaranteed across the recommended operating conditions of supply voltage and

from –40 to +85 °C unless otherwise stated. All typical values apply at VDD = 3.3 V and 25 °C unless otherwise stated.

2. The maximum data rate is dependent on the XTAL frequency and is calculated as per the formula:

Maximum Symbol Rate = Fxtal/60, where Fxtal is the XTAL frequency (typically 30 MHz).

3. Default API setting for modulation deviation resolution is double the typical value specified.

4. Output power is dependent on matching components and board layout.
