Dual-output MEMS oscillator for clock-tree consolidation
The DSC400-0401Q0103KI1T is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two independent clock outputs from a single 20-VFQFN package: 12.288 MHz and 100 MHz. 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.
