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, eliminating the need for multiple crystals for different frequencies. This approach enhances reliability, mechanical robustness, and stability, while providing superior supply noise rejection for low-jitter clock generation in noisy environments. The Si510/511 is factory-configurable for various user specifications, including frequency, supply voltage, output format, and stability, with short lead times and no NRE charges.
