Product details

33.3333 MHz MEMS XO with ±10 ppm stability

The DSC1121CM5-033.3333T: The AEC-Q100 rating confirms it passed the reliability stress tests for automotive Grade 1, meaning it can sit on an engine-control ECU or a transmission controller under the hood without derating.

Available through independent surplus distribution in lot-specific quantities; availability confirmed at RFQ.

Enable/Disable function and 35 mA supply max

An Enable/Disable pin lets the system shut down the oscillator output; when disabled the supply current drops to 22 mA max, useful for power-gated domains in battery-powered or thermal-constrained assemblies. Maximum supply current is 35 mA — the MEMS core and CMOS output buffer draw this at full speed; budget the rail accordingly, especially in multi-oscillator designs.
