Function
Voltage Supply for VCO and PA Section. It should be supplied with 3.0 V. Decoupling capacitors to the ground
plane should be placed as close as possible to this pin.
This pin is used to enable the power amplifier. It should be modulated with the OOK data in OOK mode. In
FSK mode, it should be enabled when the PLL is locked.
External Resistor. Sets charge pump current and some internal bias currents. Use 3.6 kΩ as default.
A 2.2 μF capacitor should be added at C
improves regulator power-on time but can cause higher spurs.
