The signal source is an important part in the electronic system. Along with continuous development of the electronic technical, the request of the signal source is more and more high and the traditional simulant signal source cound’t satisfy the request any more. The emergence of direct digital frequency synthesis has brought much vitality for modern electronic science and technology.This paper presents a full pipelining DDS architecture based on principle of DDS and CORDIC algorithm. Encoding with verilog HDL and synthesis, placement and routing,simulation ect..Frequency is 176.65MHz.The input frequency control word is 48 bit,the output amplitude is 16 bit,the frequency resolution is 6.27×10-7Hz.
