| Summary: | Aiming at the problem of the first frame loss and the mis-establishment of the link caused by the interference during the initial link establishment of LVDS transmission, this paper analyzes the link transmission mechanism and stability, and optimizes it from both hardware and software aspects. The software adopts the method of identifying the frame header and sending the training frame to improve the link building process. The hardware chooses a better performance electriciacl isolation chip and optimizes the differential terminal impedance to reduce the impact of interference on data transmission. Many tests have proved that the optimized link can achieve reliable transmission at a rate of 480 Mb/s. This optimized design has a good reference value for improving the transmission stability of the LVDS link and reducing errors. |
