| Abstract: | 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. |
