The DSC1101AI2-040.0000T is a MEMS-based XO (Standard) oscillator from Microchip, delivering a fixed 40 MHz CMOS output in a 6-SMD, no-lead package. Rated across -40°C to 85°C with ±25 ppm frequency stability, it suits outdoor telecom, factory-floor controllers, and engine-bay electronics where temperature swings stress quartz-based timing.
Operates from 2.25 V to 3.6 V, covering common supply rails without a separate regulator. Active draw is 35 mA max at 40 MHz; the standby current of 95 µA means the oscillator adds negligible drain during system sleep.
