Analysis of Signal Integrity on High Speed Signal Processing System of Vehicle-Mounted Video

摘要

The integrity of vehicle mounted video signal refers to all problems caused by the interconnects which transmitted by high rate. However the work frequency of the vehicle electronics becomes higher and the edge of the signal becomes increasingly steep, a larger number of interconnects can not be used as the ideal transmission line to deal with. It makes the signal integrity problems become more complex and has tremendous impact on the stability of the system. There many factors which cause signal integrity, including the signal reflection and crosstalk. In the process of the research, we combine with the advantages of differential signal, such as strong anti-interference capability, timing position accurately and so on. By the way of end termination on differential signal, we reduce the reflection and crosstalk of the signal and the signal integrity is guaranteed.
