5 Summary

This application note demonstrates how to calculate FIT rates for BAW oscillators using actual HTOL test data. As shown in these calculations, at 35 °C usage temperature, the BAW oscillator FIT rate is 0.3, which is the industry best for the oscillators across all the technologies of crystals and MEMS-based devices. A FIT rate of 0.3 is equivalent to 3.3 billion hours of MTBF. Typical crystal oscillator FIT rates are 15 to 30, indicating improved reliability in BAW oscillators in comparison to crystal oscillators with similar specifications.
