| Abstract: | In a PCB production of video processing system with its core chip is DM6467,the PCB layout between DM6467 and DDR2 and the signal integrity analysis occupy an important position, they determine the success of the entire system. As the DM6467 and DDR2 has a very high work speed, so the PCB layout between them should be high-speed PCB layout, and combine with the stack and resistance of the actual system, take special method. For the system＇s termination, crosstalk, electromagnetic compatibility, differential design etc, they need to take the signal integrity analysis with simulation software, and then modify the design to meet system requirements. |
