介绍了一种采用电磁卡箍连接器的280 Mb/s非接触车载局域网系统。基于双向传输线耦合器的电磁线夹连接器可用于实现与线夹类似的局域网连接，可抑制总线上的信号反射，实现280 Mb/s的数据速率，比最先进的车载LAN收发器快7倍。由于所有模块都以最短的距离连接，这种连接系统可以将线束重量减少30%。前向纠错是通过发送端的N-x曼彻斯特编码和接收端的多数表决来完成的。通过数字时钟恢复电路的同步接收实现了高抗噪性，该电路对噪声具有鲁棒性。通信测试在280 Mb/s下进行，10个收发器采用65 nm CMOS技术制造，通过10 m非屏蔽双绞线电缆连接。误码率和辐射谱的评估证实，ISO规范有关电磁敏感性和CISPR的电磁干扰是满意的。
A 280 Mb/s non-contact in-vehicle LAN system using electromagnetic clip connectors is presented. The bidirectional transmission line coupler based electromagnetic clip connector, which can be used to make local area network connections similar to clips, suppresses the signal reflections on the bus enabling 280 Mb/s data rate which is 7 times faster than the state-of-the-art in-vehicle LAN transceiver. Since all modules are connected with the shortest distance, this connection system can reduce wire harness weight by 30%. Forward error correction is done by N-x Manchester encoding on the transmitter side and majority voting on the receiver side. High noise immunity is achieved through synchronous receiving by the digital clock recovery circuit which is robust against noise. Communication tests were conducted at 280 Mb/s with 10 transceivers fabricated in 65 nm CMOS technology connected by a 10 m unshielded twisted pair cable. Evaluation of the bit error rate and radiation spectrum confirmed that the ISO specifications concerning electromagnetic susceptibility and the CISPR ones concerning electromagnetic interference are satisfied.
