摘要

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 -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.
