Product details

125 MHz MEMS oscillator with automotive qualification

The DSC1121DI2-125.0000T: AEC-Q100 qualified, this oscillator is suitable for under-hood automotive ECUs, ADAS camera modules, and industrial motor drives where quartz-based oscillators would fail under vibration or require longer startup times.

Supply voltage flexibility and output control

Operates from 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V logic rails without an external LDO — the wide range absorbs rail droop during cold crank or load dump.

Package and PCB footprint

Housed in a 6-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the small footprint fits tight optical module or sensor board layouts, but the no-lead land pattern requires a solder-paste stencil with 0.15 mm aperture width to avoid bridging.

Active production — no last-time-buy risk

Listed as Active on the manufacturer's lifecycle status.

Frequently asked questions

Is the DSC1121DI2-125.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification, meaning it has passed the automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up. The -40 to +85 °C temperature range covers cabin and under-hood applications.
