Product Overview
The Skyworks Si510/511 Crystal Oscillator (XO) is an advanced, IC-based frequency generation solution utilizing DSPLL technology. It offers any frequency output from 100 kHz to 250 MHz using a single fixed crystal, providing enhanced reliability, mechanical robustness, and excellent stability. This solution excels in noisy environments due to its superior supply noise rejection. It is factory-configurable for various user specifications, eliminating long lead times and NRE charges for custom oscillators. Ideal for applications requiring low jitter clock generation.
