The DSC1001AI5-018.4320 is a Microchip MEMS-based XO (Standard) delivering a fixed 18.432 MHz CMOS output with ±10 ppm frequency stability across -40°C to 85°C.
MEMS resonator vs quartz — shock and vibration advantage
The MEMS base resonator replaces a quartz crystal — no start-up time variability, no activity dips, and higher resistance to 30,000 g shock and 70 g vibration typical in automotive and industrial environments.
7.00 mm × 5.00 mm, 4-SMD no-lead exposed pad package — standard 7×5 mm oscillator footprint, reflow-compatible with standard Pb-free profiles. Seated height 0.90 mm max — fits under low-profile enclosures and mezzanine cards common in automotive ECU housings.
