摘　　要：通过对美国敏讯(Mindspeed)公司开发的CX28975芯片组的结构和特性进行介绍,分析了该芯片组的工作原理,并提出了一种利用该芯片组设计的带以太网、UART接口的G.SHDSL多速率传输设备的软硬件实现方案和程序流程,最终根据该方案实现了在一对双绞线上传输对称的、全双工的信号。The structures and features of CX28975 chipset developed by America Mindspeed are introduced, and its working principle is analyzed. In addition, the hardware and software implementation scheme and program flow of G.SHDSL multi-rate transmission equipment for Ethernet and UART interface are proposed by using this chipset. Finally, according to the proposed scheme, the symmetrical and full-duplex signal transmitting on a pair of twisted-pair is achieved.
