This replaces the need for multiple quartz oscillators or a PLL-based fanout buffer, saving board space and reducing BOM line count. The 20-VFQFN Exposed Pad package measures 5.00 mm x 3.20 mm with a 0.90 mm seated height. The supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails without an external regulator, simplifying power-tree design.","metaTitle":"DSC400-1111Q0091KI2T MEMS XO","metaDescription":"Active MEMS XO from Microchip.
