Ultra Series™ Crystal Oscillator (VCXO) Si569 Data Sheet Ultra Low Jitter I2C Programmable VCXO (100 fs), 0.2 to 3000 MHz The Si569 Ultra Series™ voltage-controlled crystal oscillator utilizes Skyworks Solutions’ advanced 4th generation DSPLL® technology to provide an ultra-low jitter, low phase noise clock at any output frequency. The device is user-programmed via simple I2C commands to provide any frequency from 0.2 to 3000 MHz with <1 ppb resolution and maintains exceptionally low jitter for both integer and fractional frequencies across its operating range. On-chip power supply filtering provides industry-leading power supply noise rejection, simplifying the task of generating low jitter clocks in noisy systems that use switched-mode power supplies.
