Outputs are configurable as LVCMOS or LVDS, letting the same oscillator feed both a high-speed SerDes reference and a lower-frequency system clock without a separate fanout buffer. Operating from 2.25 V to 3.6 V, the oscillator spans the common 2.5 V and 3.3 V logic rails without an external regulator. ## Enable/Disable function and package footprint The 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal via array under the pad for heat sinking; the 0.50 mm pitch demands careful fan-out on a two-layer board.","metaTitle":"DSC400-3111Q0088KE1 XO (Standard) MEMS Oscillator –","metaDescription":"Active Microchip DSC400-3111Q0088KE1 XO (Standard) MEMS oscillator.
