MEMS oscillator for automotive and industrial clock trees
AEC-Q100 qualification means this oscillator is validated for automotive stress conditions — temperature cycling, ESD, and latch-up — making it suitable for under-hood and chassis-domain ECUs where a quartz crystal might fail under vibration or thermal shock. The MEMS resonator inherently withstands higher shock and vibration than quartz, a practical advantage in engine bay, transmission, and suspension control modules.
Supply range and output control
Wide supply range of 2.25V to 3.6V lets the oscillator run directly from a 2.5V or 3.3V rail without an extra LDO — simplifies the power tree in mixed-voltage automotive designs. The Enable/Disable function gates the output, dropping the max supply current from 35 mA to 22 mA — useful for power-cycled sensor nodes or test-mode isolation.
Surface-mount assembly with standard reflow profiles; no special handling beyond MSL level — the MEMS die is sealed in the package, so no moisture sensitivity beyond typical SMD components.
The DSC1121 family shares the same footprint across frequency variants, so a 10 MHz sibling (e.g., DSC1121CI2-010.0000) would be a direct drop-in if the temp grade differs.
