Performance Advantages with MEMS Oscillators
The expanse of technology has by far exceeded our knowledge and perceptions. The days of slow electronic devices are no longer relevant. Time and again we have been awed by innovative technologies that help us overcome obstacles and reach our goals. Today is an era of speed and dazzling performance. Electronic devices such as digital cameras, gaming systems, tablets, laptops etc., have to be robust and reliable with advanced features that accelerate performance and provide quick accessibility in a cost-effective manner.
The simulated games are accompanied with high quality sensors and microphones to provide the customer a real-life experience. Keeping all these requirements in consideration, those who deal with the design and manufacture of these electronic items have to implement components that incorporate the desired application qualities and provide the customers with a positive experience. Thus, there is great demand for next generation solutions that are feature-rich and provide a lower total solution cost. When it comes to clocking choices, the newest and most promising technology is MEMS (Micro-Electro-Mechanical Systems) oscillators. MEMS solutions were quickly adopted into the automotive market. Applications such as tire pressure monitoring systems and air bag sensors benefited from the precision, reliability, and total solution cost.
Now the MEMS oscillator is widely used in electronic applications for various computing and electronic purposes such as laptops, DVRs, set top boxes, etc. The MEMS oscillator is revolutionizing the traditional quartz-crystal oscillator as the next generation clock timing solution for a number of reasons, but most importantly because of the superior performance and lower solution cost. It provides optimal performance and flexibility due to its ability to be programmed for any frequency within the range. It provides a simplified and enhanced inventory control and management process for supply chains. It can interface with numerous SoCs and ASSPs and operate under any standard voltage condition.
In addition to the performance and cost advantages, the MEMS oscillator offers significantly higher reliability. It features 70kG shock and 50G vibration, which represents a 10-50x improvement compared to a quartz-crystal oscillator. Furthermore, the MEMS oscillator eliminates any start-up issues and frequency dips that occur with quartz-crystal oscillators.
MEMS performance is now meeting the demands of the highest performance telecom and networking systems that could only be addressed with quartz-crystal oscillators in the past. Specifically, frequency stability as low as 0.1ppb (parts-per-billion) and phase 0.5fs (femto-second) jitter performance, combined with the lower solution cost and improved reliability make the MEMS oscillator an ideal solution for network routers, wireless and wireline telecom infrastructure equipment, and enterprise storage applications. All of these applications benefit from SiTime’s single-ended and differential oscillators.
