Supply voltage spans 2.25 V to 3.6 V, so the same part works on a 2.5 V or 3.3 V rail without a level translator on the output. ## Industrial temp grade and board-fit constraints The 20-VFQFN exposed-pad package (5.00 mm × 3.20 mm) requires a thermal land on the PCB for heat sinking; the 0.035-inch (0.90 mm) height keeps it compatible with standard mezzanine card spacing. ## Active lifecycle — no obsolescence watch","metaTitle":"DSC400-1111Q0034KI1T MEMS XO – Quad 50 MHz LVCMOS, Active","metaDescription":"Microchip DSC400-1111Q0034KI1T: quad-output MEMS XO, 4× 50 MHz LVCMOS, ±50 ppm, -40°C to 85°C, 2.25V–3.6V supply.
