针对相控阵雷达波控系统的特点 ,介绍了一种基于CY7B92 3 /93 3芯片的高速串行传输接口 ,以往的RS 485、RS 42 2传输模式 ,由于其传输速率太低已不能满足系统的要求 ,而高速串行传输方式具有上百兆的传输速率及高稳定可靠性等特点 ,将在波控系统的信号传输设计中广泛应用。文章详细分析了这组高速传输芯片的内部结构、传输机理及几种工作方式的比较 ,并讨论了这种传输方式在相控阵雷达波控系统数据传输接口中所具有的有效减少阵面走线 ,提高波束转换时间的优势

The high-speed serial transfer interface based on CY7B923/933 is introduced. The old RS-485 or RS-422 transfer mode is not used anymore because of its low-speed transfer. Now the high-speed serial transfer is used widely for beam steering system because of its hundreds MHz speed of transfer and high capability. Internal makeup, transfer theory and comparison of workmodes are analyzed in detail. Some advantages of this transfer mode in the practical application of beam steering system have been discussed.
