Shattering the Constraints of Quartz Timing to Improve Smartphones and Mobile Devices

Mobile device designers and manufacturers require components that can save space and power. The latest MEMS timing technology, such as 1 Hz to 32 kHz solutions, can reduce footprint by up to 85%, reduce power by up to 50% and increase reliability and performance. SiTime’s MEMS timing solutions are based on a programmable platform to offer additional features and a wide selection of options with very short lead times.

Clock Features for Power Conscious and Greener Applications

When designing clock sources in power conscious applications, various timing technologies and clock features should be considered as they affect power consumption differently. This paper discusses power consumption and other power-saving features, performance and layout issues; and compares the features and tradeoffs of the three main reference clock types (XTAL, oscillator and clock generator) and the two main timing technologies (quartz and MEMS).

Enhance Performance of Industrial Equipment with High-temperature, Ultra Robust MEMS Oscillators

Reference timing components are used in industrial electronic systems to synchronize all signals to the clock source. Electronic equipment used in harsh industrial environments must be highly resilient and robust, and must contain components that are designed to operate in extreme environments. Learn how MEMS-based oscillators offer new features, flexibility and superior reliability that is ideal for industrial applications.

Field Programmable Timing Solutions for Medical Applications

MEMS oscillators are well suited for meeting the special requirements (e.g., electromagnetic compatibility) of diverse electronic medical devices. Medical device applications, which tend to be highly specific, require flexible and robust timing solutions. Learn about programmable MEMS-based architecture, ultra resilient field programmable and low power devices, and features such as spread spectrum and programmable drive strength for EMI reduction.

Silicon MEMS Oscillators Provide Benefits for LED Lighting

Silicon MEMS-based oscillators are the preferred timing solution for many lighting systems, especially those used in industrial and commercial locations. MEMS oscillators have better performance and reliability compared to quartz-based devices. The flexible features and special functions in MEMS oscillators help resolve design issues. Plus MEMS timing offers lower cost and shorter lead-times for lighting manufactures.
