Working Principle

The working principle of the SI5350C-B03379-GT is based on the use of a phase lock loop (PLL), which is used to generate and synchronize multiple clock signals. The PLL consists of an oscillator, a divider and a phase detector, as well as an optional voltage controlled oscillator (VCO) or digital locked loop (DLL) to provide better stability and accuracy. The oscillator is used to produce a reference frequency, which is divided down by the divider to the required output frequency. The phase detector then compares the reference frequency to the output frequency, and adjusts the VCO or DLL to ensure that the two frequencies remain in lock-step.

In addition to the PLL, the SI5350C-B03379-GT also includes two banks of programmable frequency dividers. These can be programmed to divide the input clock frequency by a user-defined factor, allowing for more precise and accurate clock output. Furthermore, the device includes an integrated TCXO for improved frequency stability and accuracy over temperature.

Conclusion

The SI5350C-B03379-GT is an ideal choice for clock generation in a variety of applications in the telecommunications, computing, industrial and consumer markets.
