| Abstract: | In order to achieve the serial high-speed transmission of long-distance 422, it designs a transceiver module circuit that using FPGA as control chip, DS26C31 and DS26C32 as differential line drivers. It also gives the logic design of serial high-speed send and receive units by controlling the clock strictly in FPGA. After testing, the design can achieve a stable and reliable transmission in a rate of 10.3Mb/s along 45m twisted-pair. |
