Vibration is an important factor for Quartz timing applications since vibration causes significant phase noise which reduces the bandwidth in communications systems, compromises slow speed detection in radar systems and can significantly reduce the oscillator's frequency accuracy particularly in high frequency applications. Current state of the art vibration isolation systems are large and very expensive. In contrast, the IVIQ technology will consists of a micromachined vibration isolator where heaters and temperature sensors are integrated onto the vibration isolator for oven control. Commercial accelerometers will also be mounted into the system in a configuration which will allow for very precise compensation. We are targeting a total package size of 2 x 2 x0.3 cm3 and at cost of around $200/unit-more than 100 times smaller and 10 times less expensive than current state of the art systems. Furthermore, integrated shock stops will be integrated into the fabrication process which limits the deflection of the platforms making them robust to shock. Benefits: The primary benefit of the IVIQ system will be for providing vibration insensitive Quartz oscillator clock references to the military. One of the most important applications is for aircraft communications and targeting applications where vibrations for the jet, helicopter or unmanned air vehicle can reduce performance or make the system completely ineffective. This could also be applied to communications and navigation systems in ground vehicles, missiles and space satellites as well as many industrial applications. Return
