Research of Features of Synthesizer for High Speed Communication Systems

Abstract

There are analyzed two different technologies - PLL/DDS frequency synthesizers. DDS providing a fine-tunable reference for a PLL technology, and a PLL that gives the better spectrum of DDS signal output. Article presents parameters of synthesizers, and i typical application circuits are shown. Also it was proven that parameters are most important for signal source. For that purpose a statistical research is used revealing a dependence between synthesizer’s parameters improvement and its prices. The statistical research uses a regression model in Excel software environment. The functional dependences between varied parameters are relevant when analyzing technology of synthesizers and its development. The results of a research and presented graphs predict the practice of synthesizer adoption where adoption of technology S-curve tendency is obvious.
