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.
