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 replace traditional quartz or SAW technologies, enhancing reliability and accelerating product development. They are suitable for demanding clock performance requirements in communications, storage, and networking applications. The DSC1101 features a standby mode for complete power-down, while the DSC1121 disables only the outputs when the EN pin is low. Both are available in industry-standard packages and are direct replacements for 4-pin CMOS quartz crystal oscillators.
