IEC 60679-2:2026 describes the general properties, performance characteristics and usage precautions for quartz crystal oscillators. This document mainly describes crystal oscillators, but some descriptions also apply to oscillators other than crystal units (e.g. MEMS resonators).
This edition includes the following significant technical changes with respect to the previous edition:
a) some new contents that reflect the latest manufacturing technologies;
b) added contents about the operating principle of crystal oscillators;
c) added contents about usage precautions for crystal oscillators.
