Abstract :
The development of communication systems in the past years has increased the necessity to synthesize very accurate clocks, having large frequencies and very low jitter. In the same large numbers expresses the divide ratios between the frequencies of the clocks that we have to synchronize. This paper presents a new type of circuit named Direct Digitally Delay Generator (DDDG), able to synthesize frequencies up to 1 GHz with a jitter below 200 ps
