MEMS Oscillators Are Road Warriors

Microchip Technology’s DSA family of automotive-grade Micro-Electro-Mechanical Systems (MEMS) oscillators are said to 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 includes what the company says is the industry’s first multiple-output MEMS oscillator, offering a solution that can replace multiple crystals or oscillators with one device.


Available in small package sizes, the DSA1001, DSA11x1, DSA11x5 and DSA2311 offer high tolerance to mechanical shock and jarring 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°C to +125°C.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.


As the industry’s first dual-output MEMS oscillator, the DSA2311 can replace two crystals or oscillators on a board and comes in a 2.5 mm x 2 mm package. The company’s ClockWorks online configurator tool allows designers to order free samples and select the right oscillator based on frequency, package size, and temperature range.


The DSA1001 is available in a 4-pin 2.5 x 2.0 mm package for $1.07 each/10,000, and the DSA11x1/x5 is available in three 6-pin variants, starting with a 2.5 x 2.0 mm package for $1.26 each/10,000. The DSA2311 is available in a 6-pin 2.5 x 2.0 mm package for $1.61 each/10,000. For more enamoring details, visit Microchip Technology.
