Ultra Series™ Crystal Oscillator: Si549
The Si549 Ultra Series™ crystal oscillator from Silicon Laboratories offers an ultra-low jitter, low phase noise clock at any output frequency through advanced 4th generation DSPLL® technology. Featuring a phase jitter of only 95 femtoseconds, this oscillator is perfect for optical networking, 100G+ optical modules, coherent optics, broadband, data center, broadcast video, test and measurement, and FPGA/ASIC clocking applications.
The Si549 features user-programmability through I2C commands, less than 1 ppb resolution, and excellent power supply noise rejection. Specific configurations are factory-programmed at the time of shipment, eliminating the long lead times associated with custom oscillators.
