Its 2.25V to 3.6V supply range lets it run directly from 2.5V or 3.3V rails without an extra regulator — a clean fit for mixed-voltage clock trees. ## Enable/Disable function and current draw ## 6-SMD package – board-fit note Housed in a 5.00 mm × 3.20 mm 6-SMD No Lead package, 0.90 mm seated height — the footprint matches standard 6-pin oscillator land patterns, so a quartz XO swap is a direct layout drop-in.","metaTitle":"DSC1121BI2-033.3330 – 33.333 MHz MEMS XO, CMOS, Active","metaDescription":"Microchip DSC1121BI2-033.3330: 33.333 MHz MEMS XO, CMOS output, ±25 ppm, -40°C to 85°C, 2.25V–3.6V supply, 6-SMD.
