Based on this research, it has a significant realistic level. For the traditional type of phase-locked loop, it is generally a digital-analog hybrid circuit. At the process level, it has the compatibility level problem with the digital circuit under the system chip. Based on this, an all-digital phase-locked loop compatible with the digital circuit is constructed. ADPLL) has a certain value. The construction of the ADPLL can be applied to the flow of designing digital circuits, that is, the hardware description language is first compiled, and then the integrated logic is based on the extremely portable nature of the ADPLL.In the process of des...
