The DSC1121AE1-016.4000T is a 16.4 MHz MEMS-based XO (Standard) with CMOS output, built for applications that need a fixed-frequency reference with ±50 ppm stability across -20°C to 70°C.
Operates from 2.25V to 3.6V, covering 2.5V and 3.3V rails without a separate regulator — the Enable/Disable pin pulls the output to high-Z and drops supply current to 22 mA max.
The oscillator outputs a fixed 16.4 MHz CMOS clock signal.
Yes, it carries AEC-Q100 rating, making it suitable for automotive applications within its -20°C to 70°C operating range.
