The ±25 ppm frequency stability holds the clock edge jitter tight enough for 100BASE-TX Ethernet PHYs and FPGA reference clock trees without an external PLL cleanup. ## Supply voltage flexibility and enable control Runs from 2.25V to 3.6V, so it can share a 2.5V or 3.3V rail without a dedicated LDO. The enable/disable pin lets the system gate the outputs for power sequencing or test modes. ## Industrial temperature grade and package rework Rated for -40°C to 85°C, this oscillator fits outdoor telecom cabinets, motor drives, and factory-floor controllers. The 20-VFQFN with exposed pad measures 5.00mm x 3.20mm and stands 0.90mm tall. The exposed pad needs a thermal via array under the package to pull heat into the ground plane; without it the junction temp rises above the derating curve during reflow. ## Lifecycle and sourcing posture Quoted to order against your BOM quantity; availability and current pricing confirmed at RFQ.","metaTitle":"DSC400-0303Q0092KI2T Microchip MEMS XO, Dual 80 MHz LVDS","metaDescription":"DSC400-0303Q0092KI2T MEMS XO from Microchip: dual 80 MHz LVDS outputs, ±25 ppm stability, -40°C to 85°C, 2.25V-3.6V supply, 20-VFQFN.
