Working Principle

The SI5351A-B05130-GTR works by generating a highly configurable frequency synthesizer. It contains a PLL circuit and several output stages, making it capable of generating a number of clock signals of different frequencies with very low-noise and detailed user control. By connecting the inputs to external reference clocks, the user can configure a desired output frequency and generate a clock signal of that frequency.

The output stages contain a low-phase-noise voltage-controlled oscillator (VCO). This VCO receives the input clock signal and generates an output frequency with a very low noise level. The output frequency is determined by the PLL circuit, which compares the input and output frequencies, and adjusts the frequency until they are in-sync. The PLL circuit uses a feed-forward loop to minimize noise and optimize frequency stability. To further reduce noise, the output stages contain a non-integer-N divider, which can generate several outputs at frequencies even lower than the input frequency.

The SI5351A-B05130-GTR can be programmed in various ways, depending on the application. The PLL and non-integer-N divider can be used to generate complex frequency transposition and fractional-N or integer-N phase locked loop (PLL) applications. The control inputs can be programmed to control the output frequency, jitter, phase noise, and even the output current. Advanced features like clock cycles per second and duty cycle control are also available.
