  • Spread spectrum clock generating system
    Patent number: 11061430
    Abstract: A spread spectrum clock generating system is provided. The digital frequency detecting unit is configured for receiving a reference signal and a feedback signal and for comparing the reference signal and the feedback signal to generate a frequency difference signal. The digital loop filtering unit is signally connected to the digital frequency detecting unit and outputs a clock controlling signal based on the frequency difference signal. The digital spread spectrum controlling unit is configured for receiving the reference signal to output a spread spectrum signal. The digital-analog converting unit is configured for converting the clock controlling signal to a first controlling signal and for converting the spread spectrum signal to a second controlling signal. The analog controlled oscillating unit is configured for receiving the first controlling signal and the second controlling signal to output a spread spectrum clock signal.
