The MEMS resonator core gives it better shock and vibration tolerance than a traditional quartz crystal, and the 2.25V to 3.6V supply range lets it run off a 2.5V or 3.3V rail without a separate regulator. ## Package and board-fit checklist Housed in a 6-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — the same footprint as many standard 5x3.2 mm oscillators, so it's a drop-in swap for quartz XOs in that form factor. The Enable/Disable function lets you gate the output for power savings in battery-backed systems; when disabled, the supply current drops to 22 mA max from the 35 mA max active draw. Surface-mount only — the no-lead package is hand-solderable with a fine tip and flux, but a hot-air station or reflow oven is cleaner for production quantities. Suitable for new designs and production builds.","metaTitle":"DSC1121BI2-100.0000 – 100 MHz MEMS XO, AEC-Q100, CMOS","metaDescription":"DSC1121BI2-100.0000: 100 MHz MEMS oscillator, CMOS output, AEC-Q100, -40°C to 85°C.
