The 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal via pattern under the pad for heat sinking and a reflow profile compatible with lead-free solder — the exposed paddle also provides a low-impedance ground return for the high-speed outputs. It remains a current design-in choice for new builds. Operates from a 2.25 V to 3.6 V supply, covering common 2.5 V and 3.3 V rails without an external regulator.","metaTitle":"DSC400-0401Q0103KI2T MEMS XO – 12.288 MHz & 100 MHz","metaDescription":"Microchip DSC400-0401Q0103KI2T XO (Standard) MEMS oscillator with dual outputs 12.288MHz & 100MHz, ±25ppm stability, -40~85°C, 20-VFQFN.
