This replaces two discrete oscillators on the board, saving footprint and reducing BOM line count. Outputs are configurable as HCSL or LVCMOS, covering common logic families for Ethernet PHYs, FPGAs, and SoC reference clocks without a level translator. Supply voltage spans 2.25 V to 3.6 V, so the same part works in 2.5 V and 3.3 V rails without a separate regulator — common in mixed-voltage designs. ## MEMS reliability and frequency stability","metaTitle":"DSC400-0401Q0103KI1T MEMS Oscillator","metaDescription":"Microchip DSC400-0401Q0103KI1T XO (Standard) MEMS oscillator with dual HCSL/LVCMOS outputs at 12.288MHz and 100MHz.
