8.3.6 Mechanical Robustness

For reference oscillators, vibration and shock are common causes for increased phase noise and jitter, frequency shift and spikes, or even physical damages to the resonator and the package. Compared to quartz crystals, the BAW resonator is more immune to vibration and shock due to its orders of magnitude, smaller mass, and higher frequency, which means force applied to the device from acceleration is much smaller due to smaller mass.

Figure 8-12 shows the LMK6x BAW oscillator vibration performance. In this test, the LMK6x oscillator mounted on an EVM is subject to 10g acceleration force, ranging from 50 Hz to 2 kHz in x, y, and z-axis. Phase noise trace with spur due to vibration is captured using Keysight E5052B and frequency deviation is calculated from the spur power. Then the frequency deviation is converted to ppb by noting the carrier frequency and normalized to ppb/g. Finally, the RMS sum of ppb/g along all three axes is reported as the Vibration sensitivity in ppb/g. LMK6x performance under vibration is approximately 2 ppb/g while most quartz oscillators best case is 3 ppb/g and worse can be above 10 ppb/g.
