Outputs are HCSL or LVCMOS, covering the common logic levels for Ethernet PHYs, FPGAs, and SoC reference clocks without external level translation. Operates from 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails — no separate regulator needed when the board uses either supply. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the thermal pad requires a via pattern under the package for solder voiding and mechanical stability — standard QFN layout rules apply. No pin-compatible second source or direct replacement is documented; the DSC400 series is the sole reference for this order code.","metaTitle":"DSC400-4111Q0112KE2 MEMS XO – Quad Output, ±25 ppm, Active","metaDescription":"Microchip DSC400-4111Q0112KE2 XO (Standard) with MEMS resonator, four outputs (25 MHz x3, 100/156.25 MHz), ±25 ppm stability, -20°C to +70°C.
