Engineering and development of MEMS oscillators

Under this project, SiTime, an analog semiconductor company, will open a division in St. Petersburg where Russian researchers will design and develop the next generation of microelectromechanical oscillators.

SiTime products offer the advantages of exceptional temperature stability, precise digital frequency control, long service lives, and low energy consumption. Products are in high demand for infrastructure solution in telecommunications, computing, navigation systems, sensor networks for environmental control, and in other systems. The global market for synchronization devices—resonators, generators, and synchronizing chips—is currently valued at $5 billion and the Russian market, at $80 million.

Areas of application

  • Wireless and telecommunications
  • Local networks
  • Information technology
  • Consumer electronics


  • Producers of hardware and software for telecommunications and wireless networks, producers of consumer electronics, computer sciences companies

Competitive advantages

MEMS oscillators have numerous advantages over quartz oscillators:

  • Greater flexibility—on demand oscillators
  • Greater accessibility—any frequency, including fractionals
  • Smaller resonator—.5 millimeter × .5 millimeter
  • Price of oscillators declines with downsizing

SiTime specializes in systems for generating synchronization signals. Its products are used in electronic equipment for data transmission. Most of the systems employ quartz resonators that are produced and assembled individually. Quartz resonators are the sole detail that cannot be built into a CMOS integrated circuit. MEMS nanoresonators solve that problem: they can be built into any CMOS crystal that is compatible with SIP (system-in-package) or MCM (multichip module) technology.
