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. Our SC cut crystals enable high-performance acceleration sensitivity and very low phase noise.
Achieve Low Phase Noise
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 phase noise.
Bliley's low phase noise OCXO oscillators are designed to maintain low phase noise even when higher forces or acceleration are present.
