Si54x/Si56x Ultra Series™ High Performance Crystal Oscillators    

Industry’s Lowest Jitter, Widest Frequency Range, Any Frequency XO/VCXO Family    

Silicon Labs' Ultra Series™ high performance oscillators utilize our latest 4th generation DSPLL technology to provide an ultra low jitter, low phase noise clock at any output frequency up to 3 GHz. This family includes oscillators with industry-leading phase jitter as low as 80 fs (femtoseconds) for optical networking, 100G+ optical modules, broadband, data center, broadcast video, test and measurement, mil/aero and FPGA applications. These oscillators are ideal for high performance, next generation timing applications and provide the frequency flexibility, superior reliability, and super fast lead times that system designers need. Ultra Series oscillators are available with single, dual, quad, and I2C options in industry-standard 3.2x5mm and 5x7mm packages, enabling drop-in compatibility with traditional XOs and VCXOs..
