Product Overview
The Skyworks Solutions Si535/536 Ultra Low Jitter Crystal Oscillator (XO) leverages advanced DSPLL circuitry to deliver ultra-low jitter clocks at high-speed differential frequencies. Unlike traditional XOs requiring multiple crystals for different frequencies, the Si535/536 utilizes a single fixed crystal to generate a wide range of output frequencies. This IC-based approach ensures exceptional frequency stability and reliability. The DSPLL clock synthesis offers superior supply noise rejection, simplifying clock generation in noisy communication system environments. Factory-programmed at shipment, this IC-based XO eliminates long lead times associated with custom oscillators.
