CRYSTAL

The crystal is part of the oscillator that generates the reference frequency for the digital system clock and RF carrier. It is a critical
component of a Z-Wave 700 device. Further, it is mandatory to calibrate the crystal for gateway designs. Refer to section 4 for
more information.
The EFR32ZG14 has internal crystal capacitors and does not need any external circuitry apart from the crystal itself.
The ZGM130S has an integrated crystal and is calibrated at the time of production.
