Signal Integrity Analysis of a 1.5 Gbit/s LVDS Video Link

Future applications in luxury class cars may require digital video transmission with data rates as high as 1.5 Gbit/s. The signal integrity of an LVDS Serializer/Deserializer video link was investigated in this work from the viewpoint of the car manufacturer. Physically consistent simulation models for the driver, receiver, connectors, and cables were developed which are valid up to 3 GHz. Simulated and measured eye diagrams are compared and evaluated to obtain the maximum cable length as a function of data rate. Finally, the effect of pre-emphasis on the maximum cable length for various data rates was investigated.
