Product Overview
The DSC1103 and DSC1123 series are high-performance silicon MEMS oscillators offering excellent jitter and stability across a wide range of supply voltages and temperatures. These oscillators eliminate the need for traditional quartz or SAW technology, enhancing reliability and accelerating product development. They meet stringent clock performance criteria for communication, storage, and networking applications. The DSC1103 features a standby mode for complete power-down, while the DSC1123 disables only the outputs when the EN pin is low. Both are available in industry-standard packages, including a compact 2.5 mm x 2.0 mm, serving as drop-in replacements for standard 6-pin LVDS crystal oscillators.
