Product Description
Product Overview
The DSC1001/3/4 is a silicon MEMS-based CMOS oscillator family offering excellent jitter and stability. It operates from 1 MHz to 150 MHz with supply voltages between 1.8V to 3.3V and temperature ranges up to 105C. Its crystal-less design provides superior reliability against stress, shock, and vibration compared to traditional crystal oscillators, making it ideal for rugged, industrial, and portable applications. Available in industry-standard packages, it offers a pin-for-pin "drop-in" replacement for standard crystal oscillators. The DSC1003 and DSC1004 provide higher output drives of 25 pF and 40 pF, respectively.
