SiTime Corporation announced that it has entered the $2 billion precision resonator market with the ApexMEMS family of MHz resonators. These new devices are the third-generation of SiTime silicon ctechnology and are available in a variety of MHz frequencies for high-volume electronics. Mobile and IoT applications such as Bluetooth wearables 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.

According to estimates by Dedalus Consulting and SiTime, the resonator market is $3 billion in size and consists of three product categories – approximately $2 billion of precision resonators, $400 million of ceramic resonators, and $600M of SAW resonators. By 2024, industry analysts and SiTime estimate that 25 to 30 billion precision resonators will be sold, driven by the growth of connectivity in mobile-IoT, industrial-IoT, automotive, and industrial electronics. It is expected that up to 30% of these resonators will need to be very small, offer higher performance, and be easily integrated into system-in-packages and modules. This high-value market is one use case for ApexMEMS resonators.

For integration into standard IC packages and modules, ApexMEMS resonators are available as a silicon die. Co-packaging these resonators with high-performance semiconductors such as Bluetooth chips and microcontrollers gives customers a significant system and development advantage.

When using a quartz resonator, engineers face numerous challenges. Significant effort goes into matching the oscillator circuit with the resonator in the presence of unknown board parasitics. Without proper matching, performance may be suboptimal, and device startup at cold temperatures may be impacted. This situation gets even more complicated due to performance variations that are inherent in quartz resonators. An integrated ApexMEMS solution solves these challenges, reduces development time, simplifies manufacturing, and boosts system performance, reliability, and resilience.
