| Abstract: | Because of the signal-loss and signal-crosstalk,the signal integrity should be considered at the beginning of the PCB layout.Based on the high-speed general-purpose signal processing platform,the impedance matching is analyzed and simulated.The experimental result is optimized by adjusting the impedance matching resistance.It is showed that the experimental result is consistent with the reality. |
