Improve reliability and performance in harsh environments with new automotive MEMS oscillators

Microchip provides technological advancements, and the increased adoption of complex electronics systems in modern vehicles requires superior timing performance and reliability. Timing precision, accuracy and tolerance to harsh environments are essential to ensuring precise operation in today’s highly-advanced automotive systems. The company has unveiled the new DSA family of automotive grade Micro-Electro-Mechanical Systems (MEMS) oscillators that provide 20 times better reliability, 500 times better tolerance to shock and five times better vibration resistance than traditional quartz-based crystal devices. The family also includes what is claimed to be the industry’s first multiple output MEMS oscillator, offering customers a solution that can replace multiple crystals or oscillators with one device. Timing solutions with tight frequency stability over a wide temperature range are critical for applications such as ADAS, LiDAR, in-vehicle Ethernet and autonomous driving. Available in small package sizes, The company's new DSA1001, DSA11x1, DSA11x5 and DSA2311 provide high tolerance to mechanical shock, jarring and stability in harsh environments over a frequency range of 2.3MHz to 170MHz. The devices are Automotive Electronics Council Q100 (AEC-Q100) qualified with +/-20ppm stability over temperatures ranging from -40C to +125C. “Reliable, precise timing solutions are central to supporting the increasing number of electronic devices found in today’s automobiles,” said Rami Kanama, vice president of Microchip’s timing and communications group. “MEMS technology aligns with development trends in the automotive industry, and our new DSA family of MEMS oscillators and clock generators offer systems better performance, reliability and longevity.”
