Product Overview
The Skyworks Si510/511 Crystal Oscillator (XO) leverages advanced DSPLL technology to provide 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. It features superior supply noise rejection, simplifying low jitter clock generation in noisy environments. The Si510/511 is factory-configurable for user-specific requirements, including frequency, supply voltage, output format, and stability, with short lead times and no NRE charges.
