Product details

MEMS oscillator at 33.3333 MHz with CMOS drive

The DSC1121CE1-033.3333T is a standard XO built around a MEMS resonator rather than quartz — delivers 33.3333 MHz CMOS output with ±50 ppm frequency stability across the -20°C to 70°C operating range. Supply voltage spans 2.25V to 3.6V, so a single BOM line covers both 2.5V and 3.3V clock domains without a separate supply variant.

Automotive-grade qualification and package

Housed in a 6-SMD no-lead package, 3.20 mm x 2.50 mm footprint, 0.90 mm seated height. The no-lead construction eliminates solder-joint fatigue from thermal expansion mismatch on automotive PCBs.

Frequently asked questions

Is the DSC1121CE1-033.3333T AEC-Q100 qualified?

Yes, the DSC1121CE1-033.3333T carries AEC-Q100 ratings, meaning it has passed automotive-grade IC qualification including temperature cycling and reliability stress tests.
