Wide supply range of 2.25 V to 3.6 V means this oscillator can run from a 2.5 V or 3.3 V rail without a secondary regulator. Frequency stability is ±50 ppm over the -20°C to +70°C commercial temperature range — enough margin for 10/100 Ethernet, USB 2.0, and general-purpose processor clocking. ## Design-in note: 20-VFQFN layout Packaged in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height). Enable/Disable function on pin allows ganging the oscillator output with a system reset or power-good signal without an external AND gate.","metaTitle":"DSC400-1111Q0081KE1T MEMS Oscillator","metaDescription":"Active XO (Standard) MEMS oscillator.
