Experienced and familiar with variety of communication interface such SPI,I2C,UART,USB and also PCIE and memory bus(DDR2).b.Experienced and have new understanding of signal integrity.Si problems is rooted in the decrease of the signal rise time,it is a system engineering,can not be solved in one or two measures.The notion must be established,the rise time have important effects on circuit performance,must attach importance to the rise time of a signal,the signal rise along the steep,the more likely the signal integrity problems.Reflection and crosstalk are the most common SI problems in design.When impedance mutations exist on a transmission line the signal reflection occurs, so the design of impedance matching is required, otherwise can only be solved by control the tolerable range of the line length of the reflected signal. So when research the SI problems, must always pay attention to the problem of impedance.
