Abstract	LVDS (low-voltage differential signaling) technology provides an attractive solution for fast data transmission which has low power consumption. An enhanced LVDS transmission protocol is developed in this paper for reliable high-speed board-to-board LVDS data transmission in rail flaw ultrasonic testing system. The protocol, which is based on 8B/10B encoding and dynamic time-delay adjustment, avoids the data missing in AC coupling transfer between boards and guarantees the accuracy of the high-speed acquisition in receiver. Experiment results show that the enhanced LVDS transmission protocol can achieve a reliable transmission up to 1.25Gbps between boards and satisfy the requirement of high-speed data transmission in rail flaw ultrasonic testing system. The LVDS protocol designed in this paper also provides an effective transfer method for the research of portable ultrasonic testing system.
