Active MEMS oscillator for extreme-temperature and automotive duty
The DSC1121CM1-024.0000T is an active-production MEMS-based XO (Standard) from Microchip, delivering a 24 MHz CMOS clock with ±50 ppm frequency stability across the full -55°C to 125°C military temperature range. The MEMS resonator eliminates quartz startup delays and offers superior shock/vibration tolerance, making it a drop-in fit for designs that previously relied on quartz oscillators.
Supply range and enable/disable control
Operating from 2.25V to 3.6V, this oscillator spans 2.5V and 3.3V logic rails without an extra regulator — one BOM line covers both supply domains.
Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1121CM1-024.0000T fits the same land pattern as standard 3.2 x 2.5 mm quartz oscillators — no board spin needed for a MEMS swap.
