SiTime targets $2B precision resonator with MEMS technology
These MEMS resonators are 85% smaller than a typical quartz resonator, integrate load capacitors, and provide stability as good as ±20 ppm.

SiTime Corporation has entered the $2 billion precision resonator market with the ApexMEMS™ family of MHz resonators. These devices are the third-generation of SiTime silicon MEMS technology and are available in a variety of MHz frequencies for high volume electronics.

Mobile and IoT applications such as Bluetooth hearables and wearables, high-speed connectivity interfaces, asset-tracking, as well as microcontrollers, can take advantage of the 85% space savings, integration, consistent performance, resilience, and reliability that are offered by ApexMEMS resonators.

“SiTime continues to lead the timing industry with our unique expertise in MEMS, mixed-signal, analog and systems,” said Rajesh Vashist, CEO of SiTime. “By shipping almost 2 billion oscillators to date to thousands of customers, we have learned to manufacture MEMS resonators in high volume, while continuously delivering excellent quality, reliability, and performance.”

ApexMEMS-based timing devices deliver up to seven times better phase noise performance at half the power than our previous generation. At a tiny 0.42- x 0.42-mm size, the ApexMEMS resonators are 85% smaller than a typical quartz resonator, and also integrate the load capacitors. These new resonators provide stability as good as ±20 ppm while delivering superior reliability and best-in-class environmental resilience, like other SiTime devices. ApexMEMS resonators operate reliably at temperatures as high as 125ºC, a useful feature when integrated inside plastic packages.
