Working Principle

The SI5369A-C-GQ clock generator is based on a load-balanced scaled voltage controlled oscillator (VCO), a process-optimized phase frequency detector (PFD), and a multi-purpose programmable system input. It features incorporated temperature compensation, jitter attenuation, and output frequency control. The device is controlled by a few signals, including a reference clock signal, which defines the frequency of the output clock. The reference clock is fed into the PFD, where it is compared to the phase of the VCO output. The differences in phase between the two signals are then fed back to the loop filter, which adjusts the controls of the VCO in order to achieve the desired output frequency.

The SI5369A-C-GQ clock generator also features an integrated power detector. This sensor monitors the power output of the clock generator, allowing the device to automatically adjust its output to attain the highest levels of accuracy. It also features temperature compensation, which prevents changes in output frequency due to fluctuations in temperature. Finally, the device also incorporates jitter attenuation, which reduces the amount of noise present in the output signal.
