100x acceleration sensitivity improvement over standard OCXO’s

Acceleration Sensitivity

Acceleration 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.

Frequency Instability

Frequency instability due to a crystal's acceleration sensitivity impacts many aspects of oscillator performance such as:
