Abstract :
Modern commercial D/A-converters are capable of sampling frequencies up to 4000 MHz. This work has been performed to evaluate the spectral purity of a high speed DAC. The aim of the investigation is to verify if a synthesizer built up using a DAC, can match the performance of an analog PLL circuit. The following parameters have been verified: phase noise, AM-noise and spuriouses.
