Product Overview
The Skyworks Si510/511 Crystal Oscillator (XO) is an IC-based solution utilizing advanced DSPLL technology to generate any frequency from 100 kHz to 250 MHz. Unlike traditional XOs requiring a unique crystal for each frequency, this product uses a single fixed crystal and a proprietary synthesizer. This approach enhances reliability, mechanical robustness, and stability, while offering superior supply noise rejection for 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.
