Provides resistance and stability to mechanical shock and vibration across 2.3MHz to 170MHz
Reduce board space and system costs with the DSA family of small packages.

Microchip Technology Inc. (Nasdaq: MCHP) today announced the availability of its new DSA family of automotive-grade MEMS (Micro-Electro-Mechanical Systems) oscillators. These oscillators deliver 20 times better reliability, 500 times greater shock tolerance, and five times greater vibration immunity than traditional quartz-based crystal devices. They also include the industry's first multi-output MEMS oscillators, providing a solution that replaces multiple crystals or oscillators with a single device.

Timing solutions with tight frequency stability over a wide temperature range are critical for applications such as Advanced Driver Assistance Systems (ADAS), LiDAR, in-vehicle Ethernet, and autonomous driving. Microchip's new DSA1001, DSA11x1, DSA11x5, and DSA2311, available in small package sizes, provide the highest level of tolerance to mechanical shock and vibration and stability in harsh environments across the 2.3 MHz to 170 MHz frequency range. These devices are AEC-Q100 qualified, achieving +/-20ppm stability over a -40 to +125C temperature range.

“MEMS technology aligns with the automotive industry’s development trends, and Microchip’s new DSA family of MEMS oscillators and clock generators provides systems with superior performance, reliability and longevity,” said Rami Kanama, vice president of Microchip’s timing and communications group.



MEMS oscillators are manufactured using standard semiconductor processes, providing the same reliability and stability as integrated circuits in systems. Crystal oscillators are susceptible to vibration damage due to longer lead times and fixed frequencies, as they are affected by the thickness of the crystal blank within the oscillator.

This can delay product development or shipment if the customer ultimately needs to change the frequency. MEMS oscillators achieve the required frequency through programming, allowing for faster and more flexible response to new frequencies with shorter lead times. They are also suitable for mass production, helping customers meet product launch schedules.

The DSA2311 is a dual-output MEMS oscillator that can replace two crystals or oscillators on a board. This device helps customers manage their supply chain and maintain a stable BOM by solving board space constraints, reducing costs, and simplifying the design process. The DSA2311 is available in a small 2.5 mm x 2.0 mm package and is suitable for applications requiring complex boards with multiple controllers, such as infotainment systems and camera modules.

The DSA MEMS device family is part of Microchip's comprehensive automotive solutions portfolio, which includes microcontrollers, analog products, and connectivity components, allowing manufacturers to consolidate suppliers based on system requirements. All Microchip products adhere to a customer-centric end-of-life policy, ensuring long-term availability of devices for as long as customers need them.
