Supply voltage spans 2.25V to 3.6V, so it works on 2.5V or 3.3V rails without a separate regulator. Housed in a 20-VFQFN with exposed pad, the 5.00mm × 3.20mm footprint and 0.90mm height fit dense PCB layouts where vertical clearance is tight — think blade servers or compact switch designs.","metaTitle":"DSC400-3331Q0098KE1T MEMS XO – Quad Output, ±50 ppm, Active","metaDescription":"Microchip DSC400-3331Q0098KE1T MEMS oscillator: 12/50/50/50 MHz, LVCMOS/LVDS, ±50 ppm, -20°C to 70°C, 20-VFQFN.
