  • 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.

  • How to Improve Tablet PCs and Other Portable Devices with MEMS Timing Technology - Market dynamics are quickly changing with the success of the iPad, iPhone and Android-based devices. MEMS-based timing solutions enable designers to differentiate their products and meet their needs for devices with smaller size, more features, higher performance, better reliability and durability. Learn how manufacturers of portable devices can leverage both the performance advantages as well as supply chain benefits of new timing technology.

  • MEMS Timing Solutions Are Ideal for Digital Camera Applications - "Oscillators are used in cameras to clock the image sensor and main processor. Timing devices must support the increased performance and accuracy levels as camera features improve. New MEMS-based timing devices allow designers to differentiate digital cameras with enhanced performance and features. Learn how to use new timing solutions to design products with lower jitter, excellent frequency stability, smaller size, longer batter life and improved reliability."

  • MEMS Timing Solutions Improve Touchscreen Devices - MEMS-based oscillators and resonators offer new benefits to systems that use touchscreen technology. The benefits include higher system performance and reliability with immunity to shock, vibration, and noise; better touchscreen performance with lower internal EMI enabled by spread spectrum and edge rate control; lower cost with all-silicon die inside standard low-cost plastic packages; and readily available products with a wide variety of features and short lead-times.

  • MEMS Oscillators Improve System Performance and Reliability in Motor Control Applications - MEMS oscillators are replacing quartz-based timing devices in electronic motors because they offer better reliability, improved stability, more features, short lead times and lower cost. Industrial motor controlled equipment is often subject to extreme temperatures, high levels of vibration and electromagnetic noise. In the presence of these harsh conditions, oscillators must operate reliably. Read the latest performance data for XOs tested under these conditions.

  • Increase Automotive Reliability and Performance with High-temperature, Ultra Robust MEMS Oscillators - Today’s highest quality AEC-Q100 timing solutions are based on MEMS technology, a technology that is inherently more robust and reliable than quartz. MEMS-based timing solutions have low vibration sensitivity (g-sensitivity of 0.1 ppb/g), wider operating frequencies (1 to 137 MHz), extended temperature ranges (-55 to +155°C), tighter frequency stability, better packaging options, programmable features, and short lead-time at lower cost.

  • Ultra Robust MEMS Timing Solutions Improve Performance and Reliability of Smart Meters - Smart meters are often subjected to a variety of harsh operating environments.
