The design and application of one kind of multi-channel high-speed serial date acquisition system

摘要

A multi-channel high-speed serial data acquisition system based on LVDS interface is introduced. In the system,the FPGA APA300 produced by ACTEL Company used to control the serial to parallel conversion and data caching of multi-channel high-speed serial data. Then the parallel data is collected by the data acquisition card. The system can adjust itself by the standard data source generated by itself. The principle of the system,function realization of FPGA,and logic design of the LVDS interface are expounded. The system has high data acquisition rate,high reliability and strong anti-interference capability.
