125 MHz MEMS oscillator with automotive-grade reliability
The DSC1121AE2-125.0000 is a 125 MHz MEMS-based XO (Standard) oscillator from Microchip Technology, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to +70°C operating range. 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.
