The ±50 ppm frequency stability holds the timing jitter within the window required for AES3 or SDI serial streams without an external PLL cleanup. ## Industrial temperature grade for outdoor or factory-floor deployment Rated -40°C to 85°C, the DSC400-0101Q0083KI1T keeps the clock edges clean in outdoor telecom cabinets, engine-bay electronics, or factory automation panels where the ambient cycles above 70°C. The MEMS resonator is inherently more vibration-tolerant than a quartz crystal, so the oscillator holds frequency through the shock and vibration of a motor drive or a portable instrument. New designs can commit to it without a last-time-buy window, and the production line can order against the BOM quantity without obsolescence risk. The 20-VFQFN package with exposed pad requires a thermal via pattern under the centre pad — confirm the footprint matches your reflow profile before committing the board. ## Sourcing and availability for the BOM line Sourced through independent distribution, quoted to order against the BOM quantity.","metaTitle":"DSC400-0101Q0083KI1T MEMS XO – 45.1584/49.152 MHz, LVCMOS","metaDescription":"Microchip DSC400-0101Q0083KI1T MEMS XO, dual output 45.1584 MHz & 49.152 MHz, LVCMOS, ±50 ppm, -40°C to 85°C, 20-VFQFN.

These are standard audio/video sample-rate frequencies."},{"question":"Is DSC400-0101Q0083KI1T a MEMS oscillator?","answer":"Yes, the base resonator is MEMS, not quartz. This gives better vibration and shock resistance compared to a traditional crystal oscillator, and the frequency is factory-programmed — no external load capacitors needed."},{"question":"What is the difference between DSC400 and DSC600 series?","answer":"The DSC400 series is a multi-output MEMS XO with up to four independent frequencies, while the DSC600 is a single-output MEMS oscillator.
