Supply voltage spans 2.25V to 3.6V — the wide range lets it share a rail with 2.5V or 3.3V logic without a separate LDO, simplifying the power tree. Supplied on Tape & Reel (TR) for automated pick-and-place; the 6-SMD, No Lead package (5.00mm x 3.20mm) is a standard footprint shared across the DSC1122 family, so a feeder change is the only line adjustment if swapping frequencies. ## MEMS vs quartz — what the base resonator means for your build","metaTitle":"DSC1122BI2-114.2850T Microchip MEMS Oscillator 114.285 MHz","metaDescription":"Active production MEMS XO, 114.285 MHz LVPECL output, ±25 ppm stability, -40°C to 85°C, 6-SMD.
