For any design targeting IATF 16949 compliance, this is the minimum gate the oscillator must clear. The DSC1001 base product number covers a family of MEMS oscillators; the suffix DE1-030.3779 encodes the specific frequency, stability grade, and output type. ## Why a MEMS resonator over quartz? A MEMS oscillator has no crystal blank to fracture under shock or vibration — a known failure mode in automotive and industrial environments. The datasheet will show the shock and vibration ratings, which typically exceed quartz by a factor of 5–10×. For a board that sees 50 g shock or constant vibration from a motor or compressor, this is a reliability advantage. The supply voltage range of 1.8 V to 3.3 V means the same device can be used across a 3.3 V microcontroller I/O rail and a 1.8 V FPGA bank without a second oscillator variant — one line item covers both domains.","metaTitle":"DSC1001DE1-030.3779 – 30.3779 MHz MEMS XO, AEC-Q100, Active","metaDescription":"Microchip DSC1001DE1-030.3779: 30.3779 MHz MEMS XO (Standard), CMOS output, AEC-Q100 rated, ±50 ppm stability.
