Frequency Synthesizer Design and Development [Abstract] PLL frequency synthesizer circuit in the RF Communications has wide application. The detailed design of a phase-locked loop (the theory of phase-locked loop hereinafter referred to (PLL)) and the basic tenets of the main features. Design for the core component of CD4046 and 74LS90 front dividers, Implementation of high-frequency signals in the frequency of the two different phase synchronous control. Focus on the analysis of phase-locked loop input and output, and the effects of frequency response process of observing and analyzing.
