Mandatory Crystal Adjustment for EFR32ZG14/EFR32ZG23 Based Products User's Guide#
NOTE: This section replaces UG522: Mandatory Crystal Adjustment for EFR32ZG14/EFR32ZG23 Based Products User's Guide. Further updates to this user guide will be provided here.
This document describes the mandatory adjustment of the system crystal which must be performed on a product based on the EFR32ZG14 and EFR32ZG23 devices.
The purpose of this document is to describe the required method to match the system crystal of an EFR32ZG14- or EFR32ZG23-based products to the parasitic of that product. The procedure is required to ensure that the crystal tolerances of the product are within the specifications of the Z-Wave protocol.
