Its AEC-Q100 qualification means this part is validated for automotive applications, including under-hood and cabin electronics where temperature cycling and vibration are a concern. The Enable/Disable function lets the system shut down the oscillator for low-power sleep modes — the supply current drops from 35 mA to 22 mA when disabled. ## Package and supply voltage flexibility Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, it fits standard surface-mount assembly processes.","metaTitle":"DSC1121AE2-125.0000 Datasheet, Stock","metaDescription":"Microchip DSC1121AE2-125.0000 – 125 MHz MEMS XO, CMOS output, ±25 ppm stability, AEC-Q100, active.
