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.","metaTitle":"DSC1121CM5-033.3333T MEMS Oscillator – Obsolete, AEC-Q100","metaDescription":"Microchip DSC1121CM5-033.3333T XO, MEMS, 33.3333 MHz CMOS, ±10 ppm, -55°C to 125°C, AEC-Q100.
