In transmit mode, a control loop provides a common-mode voltage of 0.9V. Transistor M0 is off,
allowing the PA to set the common-mode voltage. The common-mode capacitance at each pin
to ground shall be < 30 pF to ensure the stability of this common-mode feedback loop.
In receive mode, the RF port provides a low-impedance path to ground when transistor M0, see

across the on-chip inductor can be measured at the RF pins.
XTAL1, XTAL2
The pin XTAL1 is the input of the reference oscillator amplifier (XOSC), XTAL2 is the output. A
detailed description of the crystal oscillator setup and the related XTAL1/XTAL2 pin configura-
tion can be found in
When using an external clock reference signal, XTAL1 shall be used as input pin.
