Design of Direct Digital Frequency Synthesizer Based on CPLD
Yong Tian · Acta Scientiarum Naturalium Universitatis Neimongol · 2006
The controlling model of direct digital synthesizer via CPLD is a new frequency synthesizing technology.The phase adder in the model is widely applied which could enable system to hold high frequency revolution,fast frequency switching,and easily digital modulating of the signal's phase and amplitude.
