SiTime, Silicon MEMS Oscillators and Clock Generators

Revolutionary Silicon MEMS Resonators

E-mail Print



SiTime's all-silicon MEMS resonators are at the core of SiTime's MEMS-based silicon oscillator and clock generator products. These resonators are manufactured using standard CMOS process equipment in semiconductor fabs, using silicon on insulator (SOI) wafers. The resonators are vacuum-sealed in silicon and can be packaged in cost-effective plastic packages. Read more about how SiTime's resonators are manufactured.

SiTime offers both kHz and MHz frequency resonators. With sub-uA power consumption, kHz frequency resonators are typically used for time-keeping applications (e.g. real time clocks) and power management (e.g. sleep, wake-up functions). MHz resonators are used as references in various serial and parallel protocols where data transfer speed is critical. Both resonator types have a very high Q (Quality Factor), allowing them to be used in VCXOs and TCXOs that require excellent stability and very fine frequency resolution.

Integrated Timing Functionality

SiTime's MEMS resonators are the first and only solutions that enable complete integration of timing within a semiconductor package. They can be easily and cost-effectively embedded with another SOC die inside a plastic package. This unique capability offers the benefits of increasing performance, simplifying system design, reducing technical support and increasing system reliability. SOC vendors who use SiTime's MEMS resonators can now provide a complete, embedded clocking solution without the need for any external components. Read more about resonator integration.
