*The device is operational from 1.8 V to 3.6 V. However, a supply voltage below 2.0 V is considered an extreme condition and operation can
lead to reduced output power and increased spurious emission.
1. If VDD_IO ramps cannot be guaranteed, an external reset circuit is recommended, see the AX8052 Application Note: Power On Reset
2. Internal 20 MHz oscillator, voltage conditioning and supervisory circuit running.
3. Includes Front End Module, TCXO.
