Product Overview
The Skyworks Si510/511 is a Crystal Oscillator (XO) utilizing advanced DSPLL technology to provide any frequency from 100 kHz to 250 MHz. Unlike traditional XOs, it uses a single fixed crystal and a proprietary synthesizer for enhanced reliability, mechanical robustness, and excellent stability. This IC-based solution offers superior supply noise rejection, simplifying low jitter clock generation in noisy environments. Crystal ESR and DLD are individually production-tested for guaranteed performance. The Si510/511 is factory-configurable for various user specifications, including frequency, supply voltage, output format, output enable polarity, and stability, eliminating long lead times and NRE charges.
