Si54x Ultra Series™ High Performance Crystal Oscillators    

Industry’s Lowest Jitter, Any Frequency XO    

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. This family includes oscillators with industry-leading phase jitter of only 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 they provide the frequency flexibility, superior reliability, and super fast lead times that system designers need. The Si54x Ultra Series XO’s are available with single, dual, quad, and I2C options in industry-standard 3.2x5mm and 5x7mm packages, enabling drop-in compatibility with traditional XOs.
