The DSC1121AE1-025.0000T is a MEMS-based XO (Standard) oscillator from Microchip Technology, delivering a fixed 25 MHz CMOS output with ±50 ppm frequency stability. Its AEC-Q100 qualification makes it suitable for automotive electronics where temperature cycling and vibration are routine — think engine control modules, transmission controllers, or infotainment head units that need a reliable reference clock across the -20°C to +70°C range.
Wide supply and enable/disable for power-sensitive designs
The part operates from a 2.25V to 3.6V supply, covering both 2.5V and 3.3V rails without an extra regulator.
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.
