| Abstract: | With the development of integrated modular avionics,the high-speed data transmission among avionic devices in the cabin is required. The working principle and technique characteristics of LVDS（low voltage differential signaling）are intro-duced. A scheme to adopt LVDS technique to achieve high-speed data transmission among devices in the cabin is proposed. Test result shows that the scheme′s transmission distance is more than 5 m,which indicates that the scheme is feasible. |
