Design of multi-channel high speed data acquisition system based on AD6655

This paper proposes a specific design of multi-channel high speed data acquisition system.Using AD6655 to design a 4-channels data acquisition system as an example and according to the practical application,this paper focuses on the analysis and design in the key technologies such as the matching network of A/D sampling input,the sampling clock circuit and LVDS(Low Voltage Differential Signal) data transfer.The main performances of the acquisition system has been analyzed,simulated and tested.
