Working Principle

The working principle of 5P49V5925B001NLGI8is based on PLL algorithm which enables the synthesizer to output stable clock signal with low jitter and frequency variations. The synthesizer consists of a phase/frequency detector (PFD) and a digital charge pump (DCP), as well as a digital loop filter (DLF) and programmable frequency divider (PFD).

The working process starts with the PFD, which compares the frequency and phase of the external reference clock signal with that of the output clock signal. The comparison output is used by the DCP to adjust the voltage and thus control the frequency of the input clock signal. The DLF converts the DCP analog to digital output into a more stable and predictable Settling Time (SPT) code which is then used by the PFD to program the PLL output frequency. Finally, the programmable frequency divider receives the output from the PFD and further divides the output frequency to match the required output frequency.

This process occurs in an extremely short time such that the output frequency is kept in synchronous with the external reference clock signal, thus creating a stabilized and precise clock signal with low jitter and frequency variations.
