A single oscillator replaces four discrete XOs, saving board area and reducing the number of frequency references the layout engineer must route. ## Industrial temperature range and wide supply — fits outdoor and mixed-rail designs The 2.25V to 3.6V supply range lets it run directly from a 2.5V or 3.3V rail without an intermediate LDO, simplifying the power tree and reducing BOM count. Microchip lists the DSC400-1122Q0036KI1T as Active. ## 20-VFQFN exposed pad — layout and thermal notes The 5.00 mm x 3.20 mm, 20-lead VFQFN with exposed pad requires a thermal via array under the pad for adequate heat transfer to the PCB ground plane. The 0.90 mm height fits standard mezzanine card spacing.","metaTitle":"DSC400-1122Q0036KI1T MEMS XO – 100/156.25/25/50 MHz","metaDescription":"Microchip DSC400-1122Q0036KI1T quad-output MEMS XO: 100, 156.25, 25, 50 MHz, ±50 ppm, -40°C to +85°C, 2.25-3.6V, 20-VFQFN.
