FPGA Direct Digital Frequency Synthesis Signal Generator

DDS from the concept of phase frequency synthesis is a new technology.This paper introduces the principle of DDS,presenting a solution based on a new high-capacity Stratix II Series FPGA-EP2S60 DDS System recently announced by Altera Corporation to achieve the core of the design.Matlab language will be used to convert QUARTUS Ⅱ 4.0 waveform simulation results into waveform curve.The experimental results show that use of Altera's FPGA-EP2S60 device,through a variety of measures to optimize the design development of the DDS system,achieved the desired results,with the higher performance-price ratio.
