Product details

MEMS oscillator that sidesteps quartz headaches

Automotive temperature and supply flexibility

Rated -40 to +85°C with AEC-Q100 qualification — this oscillator is at home in an engine-bay ECU, a cabin infotainment module, or an outdoor industrial controller. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without a separate regulator — simplifies the power tree on mixed-voltage boards.

Package and footprint for production reflow

Housed in a 7.00 mm × 5.00 mm 6-SMD no-lead exposed pad package — the exposed pad improves thermal conduction to the PCB ground plane, keeping the MEMS die cool during reflow and operation.

Frequently asked questions

Can DSC1121AI2-024.0000T replace a standard quartz oscillator of the same frequency?

Yes — it is a drop-in functional replacement for a 24 MHz quartz XO with CMOS output and Enable/Disable control. The MEMS resonator eliminates crystal aging and improves shock tolerance, but the pinout and supply range (2.25–3.6 V) match typical quartz footprints. Verify the Enable polarity and package footprint on your board before committing.
