The 12 MHz output is a common MCU or Ethernet PHY reference; the 3.072 MHz output aligns with telecom frame rates and audio sample clocks. A single device replaces two discrete oscillators, saving board space and reducing BOM line count. Operating from 2.25 V to 3.6 V, this XO runs on 2.5 V or 3.3 V rails without a separate regulator. The wide input range also absorbs rail ripple within that window. It is not qualified for extended outdoor or automotive ambient. The 20-VFQFN package with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height) needs a thermal via array under the pad for both electrical ground and heat sinking. Sourced through independent distribution channels.","metaTitle":"DSC400-0101Q0115KE2T XO 12MHz & 3.072MHz MEMS Oscillator","metaDescription":"Microchip DSC400-0101Q0115KE2T: dual-output LVCMOS XO, 12MHz + 3.072MHz, ±25ppm stability, 2.25V-3.6V supply, -20°C to +70°C, 20-VFQFN.
