Low G Sensitivity

G-sensitivity is a change in frequency resulting from an acceleration force applied to an frequency control device. When an frequency control device is in an application that is exposed to vibration, the frequency of the vibration will modulate the frequency degrading the phase noise. The dynamic performance of a quartz crystal resonator will degrade under adverse environmental conditions such as G forces (acceleration) or vibration. Fox Electronics has introduced the C3VR to improve Customer system performance when exposed to modern world environmental conditions. The state-of-the-art resonator incorporates Patented Technology that allow the FOX C3VR Product Series to hold system performance nearly uniform on all axes.

3D Part View
Here is a comparison of the acceleration sensitivity between a conventional quartz crystal and the Fox C3VR. As you can see from the chart above, replacing your conventional quartz crystal with the C3VR instantly gives you a massive improvement in sensitivity to acceleration. The less sensitivity to acceleration the better your phase noise. Better Phase noise means better communication and less data loss.
Conventional Frequency Control devices can show you a nice low phase noise plot, but put that same part under vibration and we get a 30 dBC/Hz difference
Put the C3VR in the same vibration conditions as the Conventional DUT and you still get the nice phase noise plot you expect. The Vibration is nearly cancelled.
