Product Overview
The Skyworks Si510/511 Crystal Oscillator (XO) leverages 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, robustness, and stability. This IC-based solution offers superior supply noise rejection for low jitter clock generation in noisy environments. Crystal ESR and DLD are individually tested for guaranteed performance. The Si510/511 is factory-configurable for frequency, supply voltage, output format, output enable polarity, and stability, eliminating long lead times and NRE charges for custom frequencies.
