Reference timing components (such as resonators and oscillators) are used in industrial systems to synchronize signals to the clock source. For several decades, reference timing components were based on quartz crystal technology— previously the only viable option that offered high stability and performance. However, over the past half-decade, MEMS (micro-electro mechanical systems) resonators and oscillators are revolutionizing the electronics industry by offering a feature-rich, cost-effective alternative to quartz crystal technology. MEMS-based oscillators are fabricated in silicon, using standard semiconductor manufacturing practices. Silicon MEMS oscillators have new features and superior reliability, both which are particularly important for industrial applications, offering unique benefits as compared to quartz crystal technology.
