Product Overview
The DSC12x2/3/4 family of high-performance oscillators leverages advanced silicon MEMS technology to deliver exceptional jitter and stability across a wide range of supply voltages and temperatures. These oscillators offer a reliable and robust alternative to traditional quartz or SAW technologies, accelerating product development and meeting stringent clock performance requirements for communications, storage, and networking applications. They feature flexible control functions for standby, output enable, or frequency selection, and are available in industry-standard footprints, serving as direct replacements for existing crystal oscillators.
