Product details

33 MHz MEMS oscillator with full military temperature range

The DSC1121AM1-033.0000T is a 33 MHz MEMS-based oscillator (XO) with CMOS output, rated across the full -55°C to 125°C military temperature range. That means it keeps running in an engine bay on a summer day or inside a satellite in LEO — environments where a standard quartz XO would drift out of spec or stop oscillating altogether.

AEC-Q100 Grade 1 — automotive and industrial deployment

It is suited for engine-control units, transmission controllers, and chassis-domain ECUs where the ambient temperature hits 105°C and the junction sees 125°C. The wide supply range of 2.25V to 3.6V lets it run directly from a 3.3V or 2.5V rail — no extra LDO needed.

Microchip lists the DSC1121AM1-033.0000T as Active. The 6-SMD, No Lead Exposed Pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm.

Frequently asked questions

Is DSC1121AM1-033.0000T compatible with 3.3V logic?

Yes. The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within the operating window. The CMOS output swings rail-to-rail, so it drives 3.3V logic inputs directly without a level shifter.
