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 its 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—that is force applied to the device from acceleration is much smaller due to smaller mass.

Figure 9-8 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. Frequency deviation is measured in Hz through the E5052 phase noise analyzer under transient mode. The measurement is then converted to ppb and normalized to ppb/g and plotted below. LMK6x performance under vibration is approximately 1 ppb/g while most quartz oscillators best case is 3 ppb/g and worse can be above10 ppb/g.
