Operating from 2.25 V to 3.6 V, the oscillator covers common 2.5 V and 3.3 V rails without an external regulator — useful when the board has multiple core voltages and the clock supply is the last rail to stabilize.","metaTitle":"DSC400-1133Q0079KI1T MEMS XO – Quad-Output, ±50 ppm","metaDescription":"Microchip DSC400-1133Q0079KI1T MEMS XO, 4 outputs (100/100/66.666/25 MHz), LVCMOS/LVDS, ±50 ppm, -40~85°C, 20-VFQFN.
