Rated -40 to +85 °C with ±50 ppm frequency stability, the oscillator keeps the four clock edges within tolerance across the industrial temperature band — no commercial-grade derating needed for motor drive or outdoor base-station applications. The 2.25 V to 3.6 V supply range lets it run from a 2.5 V or 3.3 V rail without an external regulator, simplifying the power tree in mixed-voltage designs. ## Active lifecycle, no obsolescence watch ## 20-VFQFN layout note The 5.00 x 3.20 mm, 20-lead VFQFN with exposed pad requires a thermal via array under the paddle for adequate heat sinking — the datasheet's recommended footprint includes a 3.2 x 2.2 mm pad with nine thermal vias.","metaTitle":"DSC400-2222Q0104KI1T MEMS XO – 4-Ch LVPECL Oscillator","metaDescription":"Microchip DSC400-2222Q0104KI1T quad-output MEMS XO: 125/100/200/156.25 MHz LVPECL, ±50 ppm, -40 to +85 °C, 20-VFQFN.
