It operates from a 2.25 V to 3.6 V supply rail, covering both 2.5 V and 3.3 V system power domains without an additional regulator. ## Package and layout: 20-VFQFN with exposed pad Housed in a 20-VFQFN Exposed Pad package measuring 5.00 mm x 3.20 mm with a 0.90 mm height, the exposed pad requires a thermal via pattern on the PCB to manage heat and provide a low-impedance ground return. ## Sourcing and lifecycle: active production","metaTitle":"DSC400-4244Q0069KE1 MEMS XO – 100 MHz & 161.13 MHz Quad","metaDescription":"Microchip DSC400-4244Q0069KE1 active MEMS XO, quad-output (100 MHz & 161.132813 MHz), HCSL/LVPECL, 2.25-3.6 V, ±50 ppm, -20 to 70 °C, 20-VFQFN.
