Product Overview
The Skyworks Si510/511 Crystal Oscillator (XO) leverages advanced DSPLL technology to generate any frequency from 100 kHz to 250 MHz using a single fixed crystal. This IC-based approach offers enhanced reliability, improved mechanical robustness, and excellent stability. The device provides superior supply noise rejection, simplifying low jitter clock generation in noisy environments. Crystal ESR and DLD are individually production-tested for guaranteed performance and reliability. The Si510/511 is factory-configurable for various user specifications, including frequency, supply voltage, output format, and stability, eliminating long lead times and NRE charges associated with custom oscillators.
