The DSC1121AM2-024.0000 is a 24 MHz MEMS-based oscillator from Microchip's DSC1121 series, delivering a ±25 ppm frequency stability across a -55 to 125°C temperature range — wide enough for avionics, downhole instrumentation, and under-hood automotive electronics where quartz oscillators often drift or fail from vibration. Rated AEC-Q100, it meets the reliability and temperature-grade requirements for automotive ECU, ADAS sensor, and infotainment clock trees.
Operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator — the enable/disable pin lets a microcontroller gate the oscillator output, dropping supply current from 35 mA (max) to 22 mA (max) when the clock is unused.
Housed in a 6-SMD, no-lead exposed-pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the exposed pad aids thermal transfer to the PCB ground plane, important when the oscillator runs near its 125°C limit.
