Reliability improvements that differ from traditional resonator technologies
Our BAW resonators improve traditional resonator technologies, with increased reliability in terms of vibration, shock and mean time between failure (MTBF) and failure in time (FIT) performance, which are priorities in harsh environmental conditions.
Benefits:
- BAW resonators can maintain a stability of <2ppb/g with no jitter or frequency degradation before, during or after a vibration event.
- Under a mechanical shock of 1500g, BAW resonators can maintain <0.5ppm frequency deviation and do not experience jitter degradation.
- BAW resonators have a 0.3 FIT rate or 3.3 billion hours MTBF at 35°C, equivalent to 0.3 failures over 1 billion hours of operation.

Flexible solutions for a range of output clock frequencies
Our FODs provide excellent jitter performance with a range of output clock frequencies.
Benefits:
- For clock generator products, integrating high-frequency BAW with an FOD in packages as small as 3mm by 3mm generates clocks with frequencies from 1MHz to 400MHz.
- Spread-spectrum clocking integrated into the FODs reduces system electromagnetic interference.
- Glitchless output-frequency programmability with <10ppb resolution steps using FODs provides precise output clock frequency adjustment.
- FODs used as a startup clock are programmable to output swing or output type at the vendor factory or on-site using the I2C interface.
