APPLICATION NOTE 5589

Industry Turns to MEMS for Accurate Real-Time Clocks

By: Paul Nunn

Abstract: Real-time clocks (RTCs) continue to evolve, keeping pace with changes in their use and application by becoming smaller and more accurate. A major driver behind this evolution and adaptation is a new resonator technology—microelectromechanical systems (MEMS). This application note explores advancements in timekeeping accuracy, and examines the trends, concepts, and characteristics of more accurate real-time clocks.
