Silicon MEMS oscillator MICROCHIP DSC1101BM2-PROG designed for communication and storage applications
Product Overview
The DSC1101 and DSC1121 series are high-performance silicon MEMS oscillators offering excellent jitter and stability. They provide a reliable and advanced alternative to traditional quartz or SAW technologies, accelerating product development and enhancing reliability. These oscillators are designed for demanding communications, storage, and networking applications, featuring a wide operating temperature range, high supply noise rejection, and a broad frequency range. The DSC1101 includes a standby feature for complete power-down, while the DSC1121 disables only the outputs when the EN pin is low. Both are available in industry-standard footprints and are direct replacements for standard 4-pin CMOS quartz crystal oscillators.
