Microchip's automotive MEMS oscillators for improved reliability and performance in harsh environments
Microchip Technology Inc. unveiled its new DSA family of automotive grade microelectromechanical systems (MEMS) oscillators that are designed 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 company says that 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.
Available in small package sizes, Microchip's DSA1001, DSA11x1, DSA11x5 and DSA2311 reporteldy 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 C.
MEMS oscillators are built entirely with standard semiconductor processes, bringing systems reliability and stability. MEMS oscillators achieve frequency through programming, giving them flexibility to quickly support new frequencies with shorter lead times, as well as to ramp in volume to help customers meet product launch schedules.
The DSA2311 can reportedly replace two crystals or oscillators on a board. The device is intended to address board space limits, save costs, and ease the design process. The DSA2311 comes in a 2.5 mm x 2.0 mm package and is suited for applications that require a complex board with multiple controllers, such as infotainment systems and camera modules.
All products are available now for sampling and in volume production. The DSA1001 is available in a 4-pin 2.5 x 2.0 mm package, and the DSA11x1/x5 is available in three 6-pin variants, starting with a 2.5 x 2.0 mm package. The DSA2311 is available in a 6-pin 2.5 x 2.0 mm package.
