Product details

MEMS oscillator replaces quartz at 120 MHz

The DSC1121AI2-120.0000 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 120 MHz CMOS output with ±25 ppm frequency stability.

Industrial temp and automotive grade

The AEC-Q100 rating means it passed the thermal cycling, vibration, and ESD stress tests required for under-hood and chassis-mounted modules.

Operates from 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without a separate regulator.

Listed as Active with no end-of-life notice.

Frequently asked questions

How can I order DSC1121AI2-120.0000 or check availability?

The part is Active and in production. Submit an RFQ with your target quantity and lead-time window; we source through independent distribution and confirm pricing and stock at quote time.

Is DSC1121AI2-120.0000 available in tape and reel packaging?

The listed package is Tube. Tape and reel availability is not confirmed in the current record; confirm packaging preference at RFQ.

Can DSC1121AI2-120.0000 replace a standard quartz oscillator?

Yes — the MEMS resonator is a drop-in replacement for quartz in the same 6-SMD footprint. The ±25 ppm stability matches typical quartz performance, but the MEMS part offers better shock and vibration tolerance and eliminates quartz start-up time.
