Two MEMS oscillators are designed for ASIL

Two families of robust AEC-Q100-qualified MEMS oscillators, the SiT2024/25 and SiT8924/25 are designed for ASIL (Automotive Safety Integrity Level) -compliant automotive applications such as advanced driver assistance systems (ADAS), in-vehicle Ethernet, powertrain and electronic control units (ECUs).

Using the company’s silicon MEMS, analogue technology and standard semiconductor packaging provide timing solutions that deliver the highest reliability and dynamic performance under extreme temperatures, shock and vibration, says the company.

The SiT2024/25 oscillators are optimised for under-the-hood systems such as engine control, transmission control, active suspension control, electronic steering and other ECUs. They are available in a SOT23-5 leaded package to enable visual inspection and the best solder joint reliability, especially in hot and cold environments. The SiT8924/25 oscillators are available in industry-standard QFN footprints as small as 2.0 x 1.6mm for camera modules and other small form factor systems.

The oscillators are AEC-Q100 qualified, Grade 1 (-40 to +125 degree C), Grade 2 (-40 to +105 degree C) and extended temperature range (-55 to +125 degree C). Frequency stability is ±20ppm for best timing margin.

Supply voltage options are 1.8, 2.5 to 3.3V
