摘　　要：介绍了一种基于ASI编码的高速数据传输接口设计方案。该传输接口利用NS公司的CLC007和CLC014芯片进行发送驱动和接受均衡,利用CYPRESS公司的CY7B923和CY7B933芯片进行编码和解码,采用ALTERA的FPGA实现数据缓冲与转换的功能,并通过对数据的分组打包和解包校验的方法,保证数据的完整性及正确性。编码产生的数据利用50Ω阻抗匹配的同轴电缆进行传输,传输速率最高可达400 Mbps,传输距离最远可达200 m。The design scheme of high-speed data transmission interface based on ASI coding is introduced. The transmission interface uses CLC007 and CLC014 chips of NS company to perform send driving and receive equalization, CY7B923 and CY7B933 chips of CYPRESS company to hnplement coding and decoding, FPGA of ALTERA company to realize the functions of data buffering and conversion, and data packaging and unpacking to ensure the integrality and correctness of data. The data generated after coded are transmitted through 501~ coaxial cable with impedance matching, while the transmission rate can be up to 400Mbps and the transmission distance can be up to 200m.
