Product Overview
The DSC1101 and DSC1121 series are high-performance silicon MEMS oscillators offering excellent jitter and stability across a wide range of supply voltages and temperatures. These oscillators provide a reliable alternative to traditional quartz or SAW technologies, accelerating product development and enhancing reliability for demanding communication, storage, and networking applications. The DSC1101 features a standby mode for complete power-down, while the DSC1121 disables outputs when the EN pin is low. Both are available in industry-standard packages and are direct replacements for standard 4-pin CMOS quartz crystal oscillators.
