Abstract :
Direct digital synthesizers with the built-in multipliers of clock frequency are investigated in the article. The mathematical model of power spectral density of phase noise is received, noise characteristics of integrated direct digital synthesizer are investigated, comparison with experimental characteristics is carried out.
