MEMS CMOS Oscillator MICROCHIP DSC1001DI2-004.0960T with Enhanced Reliability and Wide Voltage Range
Product Overview
The DSC1001/3/4 is a silicon MEMS-based CMOS oscillator family offering exceptional jitter and stability performance across a wide range of supply voltages and temperatures. Designed with an all-silicon resonator, it provides superior robustness and immunity to stress-related fractures compared to traditional crystal oscillators. This crystal-less design enhances reliability, making it ideal for rugged, industrial, and portable applications subjected to stress, shock, and vibration. Available in industry-standard packages, the DSC1001/3/4 offers a pin-for-pin "drop-in" replacement for standard crystal oscillators, facilitating easy integration. The DSC1003 and DSC1004 models provide higher output drive capabilities (25 pF and 40 pF, respectively) compared to the DSC1001.
