Design of High-Speed Information Transmission Equipment Based on IEEE1394 Bus

In this paper, a design plan of the high-speed information transmission has been brought forward. The equipment which adopts open-style interface design can be used for the transmission of the audio and video information, as well as the high-speed datas information. The DSP chip is used as the controller of the information transmission system, and two 1394 chips are used as link layer and physical layer devices respectively. In the process of PCB board design, an anti-interference design which can improve the system stability has been added specially. Experiment shows that the transmission of the video information and the high-speed datas information can be realized by the transmission equipment. The equipment has good generality, and gets fine effect in actual application.
