Frequency stability of ±25 ppm across temperature and supply variation keeps the clock edges within tight timing budgets for 100 MHz+ serial interfaces and high-speed ADCs. ## Active lifecycle supports volume procurement and new designs The part can be designed in today and sourced for production without lifecycle risk.","metaTitle":"DSC400-1111Q0084KI2T MEMS Oscillator – Quad LVCMOS Output","metaDescription":"DSC400-1111Q0084KI2T from Microchip: quad-output XO with 33.33/50/125/100 MHz LVCMOS, ±25 ppm stability, -40°C to 85°C.
