Its 2.25V to 3.6V supply range lets it run off a 2.5V or 3.3V rail without an intermediate regulator, and the ±50 ppm frequency stability keeps the clock edge jitter within the timing budget for 100 MHz SERDES or DDR interfaces. ## Industrial temperature grade and package fit Rated for –40°C to +85°C, this oscillator suits outdoor telecom cabinets, factory-floor controllers, and engine-bay-adjacent electronics where the ambient temperature cycles daily. The VFQFN with exposed pad requires a thermal via array under the pad for heat sinking — the datasheet recommends a via pattern tied to the ground plane. An Enable/Disable pin lets the system shut down unused clock lanes for power savings during sleep modes. ## Active lifecycle and sourcing posture It is available for both new design-ins and production replenishment through independent distribution. Quoted to order against your BOM quantity; availability and current pricing confirmed at RFQ. No pin-compatible second source is listed, but the DSC400 family shares the same footprint across frequency configurations — the base product number DSC400 covers the series.","metaTitle":"DSC400-1444Q0060KI1 MEMS XO – 100MHz/25MHz Quad Output","metaDescription":"Microchip DSC400-1444Q0060KI1: MEMS-based XO, 100MHz (×3) + 25MHz outputs, HCSL/LVCMOS, 2.25V–3.6V, ±50ppm, -40°C–85°C, 20-VFQFN.
