MEMS active resonators replace quartz crystals
XCalibur is a line of MEMS active resonators that can be programmed as drop-in replacements for quartz crystal resonators.
Quartz crystal resonators have weaknesses such as being susceptible to strong EMI fields and requiring negative resistance testing in every design and layout cycle, as well as requiring qualification for each frequency.
XCalibur active resonators from SiTime Corp. (Santa Clara, Calif.) allow customers to implement a new frequency in the same design without re-qualifying the part, the company claims.
SiTime XCalibur active resonators provide 10x better reliability than quartz, making them ideal for automotive and industrial applications that demand robustness and long life in harsh environments. The many benefits of these MEMS-based resonators also extend to communications and networking, enterprise, consumer electronics, mobile and IoT, and aerospace and defense applications.
The SiTime XCalibur active resonators can replace 4-pin SMD crystal resonators in demanding automotive, industrial, and enterprise equipment applications. They provide excellent stability, greater reliability, reduced BOM, and ease of design.
