1. Typical value reflect average measurements at midpoint of voltage range, 25 °C only. See
2. No more than 10% duty cycle deviation from 50%.
3. Use fundamental mode only, do not use overtone crystals or overtone ceramic resonators.
4. Due to variations in electrical properties of external components such as, ESR and Load Capacitance, operation above
5. Consult crystal vendor data sheet.

16 MHz is not guaranteed for all crystals or ceramic resonators. Operation above 16 MHz requires that a Negative Resis-
tance Margin (NRM) characterization and component optimization be performed by the crystal or ceramic resonator vendor
for every different type of crystal or ceramic resonator which will be used. This characterization and optimization must be
performed at the extremes of voltage and temperature which will be applied to the microcontroller in the application. The
NRM must meet or exceed 10x the maximum ESR of the crystal or ceramic resonator for acceptable performance.
