The NCO as a Stable, Accurate Synthesizer The NCO as a Stable, Accurate Synthesizer Technical Brief May 1998 TB318.1 Low Jitter Frequency Reference In communication and other circuits, it is often necessary to clock rate. This is not cost effective for applications requiring produce an accurate reference signal whose frequency and phase jitter of less than 5ns, however, since it requires a phase can be precisely controlled in real time. The sample rate of 200 Mega Samples Per Second ……
