The SI5350A-B06879-GTR is a versatile device, suiting a wide range of applications, from audio and video systems to telecoms and test equipment.The accuracy and flexibility of the output clocks make it ideal for testing and measurement applications, where tight tolerances can be required on clock outputs.In addition, its range of clock outputs and potential scalability makes it useful for radio frequency applications, as well as digital signal processing, where precise synchronization of clock signals can be required.

Working Principle

The SI5350A-B06879-GTR uses a digitally adjustable loop filter and voltage-controlled oscillator (VCO), along with its onboard crystal oscillator, to control the frequency of its output clock.The on-chip oscillator is used to provide the reference frequency, which is then compared to the incoming reference signal. The frequency of the reference signal is measured, and the loop filter adjusts the voltage value of the VCO to maintain the frequency match.This VCO will adjust its frequency according to the frequency difference, in a process known as phase-locked loop or frequency synthesising. The output clock maintains the same frequency as the reference signal, despite any changes in its frequency.The SI5350A-B06879-GTR then uses its integrated loop filter to adjust the voltage to ensure that the clock signal is maintained with a minimum amount of jitter. The loop filter provides additional filtering and stability, and is adjustable to match the requirements of various applications.In summary, the SI5350A-B06879-GTR is a versatile and powerful clock/timing device, offering both accuracy and flexibility for a wide range of applications. Its highly adjustable phase-locked loop and digital loop filter ensure that the frequency of the output clock is maintained with minimal jitter. As such, it is well-suited for audio and video systems, radio frequency applications, and digital signal processing.
