摘　　要：异步串行接口(ASI)因为其高速且可靠等优点被广泛应用于多个场景。传统的ASI链路层都是通过CYPRESS公司生产的CY7B933/923芯片设计电路实现的,该芯片设计方法虽然简单易操作,但芯片价格昂贵,且该芯片已经停产,文章采用价格低廉国产化芯片即EG4A20BG256芯片进行电路设计,给出设计参考电路图,从而达到视频图像传输与接收目的。Asynchronous serial interface(ASI)is widely used in many scenarios because of its high speed and reliability.The traditional ASI link layer is realized by cy7B933/923 chip design circuit produced by CYPRESS Company.Although the chip design method is simple and easy to operate,but the chip is expensive,and the chip has been discontinued.In this paper,the low-cost domestic chip,namely EG4A20BG256 chip,is used for circuit design.The design reference circuit diagram is given to achieve the purpose of video image transmission and reception.
