Working Principle

The overall working principle of the SI5335B-B04282-GM is based on a phase-locked loop (PLL) system. It uses an input clock and generates a different frequency on its output. The PLL takes the input clock signal, multiplies and/or divides it by a fractional or integer frequency divider, and then compares this divided signal with an internal reference clock. The output is then adjusted by measuring the difference between the two signals and changing the feedback loop accordingly.

The PLL consists of a VCO (Voltage Controlled Oscillator), a programmable frequency divider, a phase comparator, a charge pump, and loop filter components. The VCO is an oscillator that produces an output signal whose frequency and phase is determined by the input voltage. The frequency divider is a programmable counter that divides the VCO output frequency by an integer factor. The signal produced is then compared to the reference clock by a phase comparator and the difference signal is sent to the charge pump, which provides a signal to the loop filter. The loop filter adjusts the voltage level, which changes the VCO frequency and allows the PLL to adjust to match the reference frequency. Once the PLL has achieved lock, the output frequency is determined by the voltage applied to the VCO.

The SI5335B-B04282-GM also includes integrated Voltage Controlled Crystal Oscillator (VCXO). This is used to achieve improved accuracy and stability with minimal effort. It is integrated with a VCXO which allows users to fine tune the output frequency based on an external voltage source.
