摘　　要：为了提高以太系统的传输速度,主要对以太网物理层收发器模块进行了相关研究.在收发器模块中,采用了串并转换、4B/5B编码等并行编码方式替代了普通的曼彻斯特编码方式,将数据并行输出.并行传输方式与传串行传输相比,可在相同时钟频率内提供更多的有效数据,从而提升系统的传输速度.仿真结果表明,收发器模块在25 MHz时钟下实现了100 Mbit/s的收发速度,大幅提高了传输效率.In order to improve the transmission speed of Ethernet system,the Ethernet physical layer transceiver module was studied and discussed.Parallel encoding methods,such as serial-to-parallel conversion and 4B/5B encoding,were used to replace the ordinary Manchester encoding method in the transceiver module for parallel data output.Compared with serial transmission,parallel transmission can provide more effective data within the same clock frequency,thereby improving the transmission speed of the system.The simulation results show that the transceiver module achieves a transceiver speed of 100 Mbit/s at 25 MHz clock,which greatly improves the transmission efficiency.
