Outputs are HCSL or LVPECL compatible, and the device includes an Enable/Disable function for power management. The MEMS resonator eliminates quartz crystal startup issues and offers better shock/vibration immunity in industrial environments. Supply voltage spans 2.25V to 3.6V, so it runs on 2.5V or 3.3V rails without a separate regulator. ## Package dimensions and footprint Housed in a 20-VFQFN with exposed pad, the body measures 5.00mm x 3.20mm x 0.90mm.","metaTitle":"DSC400-4244Q0069KE1T MEMS XO – 100MHz & 161.13MHz Quad","metaDescription":"Microchip DSC400-4244Q0069KE1T MEMS XO, 100MHz & 161.1328125MHz outputs, HCSL/LVPECL, 2.25-3.6V, ±50ppm, -20°C~70°C, 20-VFQFN.
