Silicon MEMS Oscillator MICROCHIP DSC1101DM1-012.0000 with Industry Standard Package and Standby Mode
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 are designed to replace traditional quartz or SAW-based solutions, enhancing reliability and accelerating product development. They 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 when the EN pin is low. Both are available in industry-standard packages, including a compact 2.5 mm x 2.0 mm footprint, serving as direct replacements for standard 4-pin CMOS quartz crystal oscillators.
