摘要
针对在测试环境恶劣情况下数据高速远距离串行通信场合传输过程中可靠性低的问题,提出了一种基于CY7B923/933的可纠错HOTLink数据传输方案。该方案设计了数据收发器的外围电路,且在逻辑中设计加入了BCH编解码,通过使用纠错技术,极大地提高了传输的可靠性。经验证,该系统中HOTLink数据在60℃高温且有脉冲激励干扰情况下,可实现330 Mbit/s传输速率在200 m同轴电缆上无误码传输。
Focused on the low reliable problem of data existing in high-speed and long-distance circumstance of serial communication transmission process in adverse testing applications,a method of data transmit scheme of HOTlink with the function of error correction based on CY7 B923/933 was proposed.The method designed the peripheral circuit of data transceiver.And in logic design,BCH coding was added to improve the reliability greatly in data transmission by using the error correction technology.Through the verification,in the temperatuer of 60℃and being disturbing by the pulse excitation,errorfree transmission of HOTLink data can be realized at the rate of 330 Mbit/s and on 200 m of coaxial-cable in the system.
