SiTime Corporation, a MEMS and analog semiconductor company and a wholly owned subsidiary of MegaChips Corporation (Tokyo Stock Exchange: 6875), offers MEMS-based silicon timing solutions that replace legacy quartz products. With 90% market share and over 400 million devices shipped, SiTime is driving the electronics industry to use 100% silicon-based timing.

Broad-based Adoption

Timing products provide the heartbeat of all digital electronic systems. SiTime products are used in all major market segments by more than 1000 customers in over 100 applications. Our highest volume designs are in the networking, consumer, computing and storage segments. In 2011 we began to offer products for telecom, wireless and industrial applications. SiTime entered the smartphone market in 2013 with the first MEMS oscillators for mobile phones, and is now experiencing rapid growth in wearables and IoT applications.

Making it Better – Higher Performance, Lower Power, More Reliable, Lower Cost

SiTime has transformed the timing market. For the past several decades, quartz crystal based oscillators, clock generators and resonators were the primary reference timing components in electronics. As there were no alternatives, OEMs and ODMs accepted the inherent limitations of quartz timing devices. Now, with robust MEMS resonators and high performance analog ICs, SiTime has developed breakthrough solutions that overcome the limitations of quartz devices.   

Making it Easier – Programmable, Drop-in Replacements

We make it easy for OEMs and ODMs to use SiTime products. Our QFN oscillators are 100% drop-in replacements for quartz oscillators without requiring any board changes. Plus, our programmable architecture enables the most flexible products with more features and ultra fast lead-times. SiTime solutions are an easy choice – once our customers use SiTime products, they rarely go back to quartz.

Making it Smaller – Up to 80% Space Reduction

SiTime is enabling the miniaturization of electronic products by offering timing solutions in the industry’s smallest packages – as small as 1.5 x 0.8 mm – and unique features that reduce component count. Our products reduce board space by combining the functionality of multiple components in the same package. Semiconductor companies are integrating our silicon MEMS resonators within their SOCs/ASICs to completely eliminate external clocks and simplify system design.
