Acceleration SensitivityAcceleration Sensitivity is a crystal oscillator's inherent sensitivity to external forces applied in any direction. Quartz crystals have a very special place in our hearts at Bliley. They literally provide the heartbeat of the timing electronics we've all come to rely on daily.
The cool thing with quartz crystals is that if you apply a voltage, the quartz will begin to vibrate. The down-side is that if you apply a vibration, the quartz will produce a voltage. This voltage shows up as phase noise and is a real drag.
The magnitude of this phase noise or frequency deviation is directly proportional to the amount of force or acceleration applied…the higher the force > the greater the frequency instability > the greater the noise.
