FlexRay总线作为新一代车内控制总线具有很好的实时性与可靠性。分析了FlexRay总线的特点，以TMS320F28335、MFR4310与TJA1080建立了FlexRay节点，针对当前电子通信系统的电磁兼容（EMC）问题，提出了在FlexRay节点驱动电路中加入数字隔离器、共模扼流圈、分离端接的方法，提高了整个FlexRay节点的EMC性能。

The TJA1080 is a FlexRay transceiver, which is compatible with the FlexRay electrical physical layer specification V2.1 Rev. A (see Ref. 1). It is primarily intended for communication systems from 1 Mbit/s to 10 Mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a FlexRay network. The TJA1080 can be configured to be used as an active star transceiver or as a node transceiver. The TJA1080 provides differential transmit capability to the network and differential receive capability to the FlexRay controller. It offers excellent EMC performance as well as high ESD protection. The TJA1080 actively monitors the system performance using dedicated error and status information (readable by any microcontroller), as well as internal voltage and temperature monitoring. The TJA1080 supports the mode control as used in Philips TJA1054 (see Ref. 2) and TJA1041 (see Ref. 3) CAN transceivers.
