5 Summary

Based on the sinusoidal, random vibration and Mechanical Shock tests and the test results shown in this application note, the following are key observations.

  • BAW oscillators are not damaged and work normally during and after sinusoidal, random vibration, and mechanical shock tests.
  • Based on the sinusoidal vibration test, the vibration sensitivity for the BAW oscillators is less the 2 ppb/g across all type of packages, as well as single-ended and differential-ended output types.
  • Based on the random vibration test, the jitter is not degraded and the device performance has no significant variations before, during, and after the test.
  • Based on the mechanical shock test, the ppm variation during the 1500 g acceleration test is less than 0.5 ppm.

These results show that BAW oscillators are robust and highly reliable and immune to the vibration and mechanical shock.
