Design of High Speed Multi-Channel Sampling Board Based on AD9680

本文设计了一种基于AD9680的高速多通道采样板,通过AD采集雷达信号,将雷达信号通过FPGA存储在DDR3中,FPGA可以调用DDR3中数据进行数据处理,同时采样数据及处理完成数据可以通过光纤接口导出到外部存储设备。AD9680采样速率可高达1GHz,支持高达2GHz的中频信号采样,可以满足大多数采样需求。

In this paper, a high-speed multi-channel sampling board based on AD9680 is designed. Radar signals are collected by AD and stored in DDR3 through the FPGA. The data in DDR3 can be processed by the FPGA. At the same time, the sampled and processed data can be exported to external storage devices through the optical fiber interface. The sampling rate of AD9680 can be as high as 1 GHz, and it supports the sampling of intermediate frequency signals up to 2 GHz, which can meet most of the sampling requirements.
