Product Overview

The DSC1103 and DSC1123 series are high-performance silicon MEMS oscillators offering exceptional jitter and stability across a broad range of supply voltages and temperatures. These oscillators leverage MEMS technology to enhance reliability and accelerate product development, providing a superior alternative to traditional quartz or SAW devices. They are designed to meet stringent clock performance requirements for demanding communications, storage, and networking applications. The DSC1103 features a standby mode for complete power-down, while the DSC1123 disables only the outputs. Both are available in industry-standard packages, including a compact 2.5 mm x 2.0 mm footprint, serving as direct replacements for standard 6-pin LVDS crystal oscillators.
