Product Overview
The DSC1101 and DSC1121 series are high-performance MEMS oscillators offering excellent jitter and stability across a wide range of supply voltages and temperatures. These oscillators leverage proven silicon MEMS technology, providing enhanced reliability and faster product development compared to traditional quartz or SAW technologies. They are designed to meet stringent clock performance criteria for various communications, storage, and networking applications. The DSC1101 features a standby mode for complete power-down, while the DSC1121 disables outputs. Both are available in industry-standard packages, serving as direct replacements for standard 4-pin CMOS quartz crystal oscillators.
