IDT MEMS oscillator commercializes piezoelectric resonators

November 30, 2011 – BUSINESS WIRE — Mixed-signal semiconductor supplier Integrated Device Technology, Inc. (IDT, NASDAQ:IDTI) developed and demonstrated commercially available oscillators incorporating piezoelectric micro electro mechanical system (pMEMS) resonators.

The IDT pMEMS resonator uses piezoelectric material and single-crystal silicon, which provides stability and low damping. IDT holds or is waiting on more than 40 patents related to the MEMS technology. The company says its passive pMEMS resonator is the world’s smallest hermetically sealed wafer level package (WLP) resonator. pMEMS oscillators will be available in industry-standard pin- and function-compatible plastic packages.

pMEMS resonators have "high native frequencies," which IDT capitalizes on to replace traditional quartz-based oscillators for cloud computing designs requiring high reliability and resistance to shock and vibration, consumer applications requiring multiple outputs, and communications and networking equipment that need low phase jitter. Ted Tewksbury, Ph.D., president and CEO of IDT, called MEMS a "natural step" in the company’s silicon timing product progression.
