Active Resonators

SiTime XCalibur™ active resonators are designed to replace 4-pin SMD crystal resonators in demanding applications such as automotive, industrial, and enterprise equipment. They provide excellent stability over a wide temperature range, greater reliability, reduced BOM, and ease of design. With short lead times and the elimination of design issues related to quartz crystal resonators – such as cold startup, EMI problems, the need for motional impedance (ESR) and negative resistance testing at every design and layout cycle – these active resonators greatly reduce time to market. These resonators also eliminate the need for tuning capacitors required for parallel resonant XTALs. And as an active device, they can drive two clock inputs, further reducing component count.

MHz MEMS Resonators

SiTime ApexMEMS™ MHz resonators, based on our third-generation MEMS technology, are suited for high volume, space-constrained mobile and IoT applications like Bluetooth hearables and wearables, high-speed connectivity interfaces, asset-tracking, and microcontrollers. These resonators come in popular MHz frequencies and are 85% smaller than a typical quartz resonator. The SiTime ApexMEMS resonators can be integrated into standard IC packages or modules, simplifying design and manufacturing. They offer better reliability, higher performance, and environmental resilience in a small size. By replacing traditional crystal resonators, these MEMS devices simplify design, reduce board space, and improve system reliability and robustness.
