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 provide a reliable and advanced alternative to traditional quartz or SAW-based devices, accelerating product development and enhancing reliability. They are designed for demanding communications, storage, and networking applications, featuring low current consumption, wide frequency ranges, and industry-standard footprints. The DSC1103 includes a standby mode for complete power-down, while the DSC1123 disables outputs when the enable pin is low.
