Microchip announces 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. Microchip Technology 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 DSA family also includes 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 Advanced Driver Assistance Systems (ADAS), Light Detection and Ranging (LiDAR), in-vehicle Ethernet and autonomous driving. Available in small package sizes, Microchip’s new DSA1001, DSA11x1, DSA11x5 and DSA2311 offer the highest tolerance to mechanical shock, jarring and stability in harsh environments over a frequency range of 2.3 MHz to 170 MHz. The devices are Automotive Electronics Council Q100 (AEC-Q100) qualified with +/-20 ppm stability over temperatures ranging from -40 to +125 degrees Celsius.
 
“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.”
