The Design of High Performance Signal Source Based on DDS and PLL

Ran Ding

Abstract

This design is based on the Direct Data Frequency Synthesis(DDS) technology,and FPGA is used to control the AD9910.A kind of design of high performance signal generator is given.The DDS basic principle,the selection of oscillator,the approach of suppressing the dispersion,the overall structure of the system and the software design are mainly described.The output is easy to control,has high frequency,resolution and precision,and it has wide application in the future.
