    Abstract:

    In view of the situation of data error and number loss in high-speed long-distance transmission in bad test environment, this design adopts a BCH code which can self-correct error and a 8B/10B code which can realize the DC balance in the transmission process. In this scheme, the long-distance data transmission is realized by using the high-speed serial Hotlink transmission and receiving chip CY7B923/933, and the reliability of the transmission process is improved by designing the hardware circuit of data receiving and sending and using the software logic design with error correction technology. After the high temperature test with external signal excitation and interference, it can realize the correct transmission of Hotlink data on the 100M coaxial cable at the rate of 400Mbit/s without error code.
