| Abstract: | The problem of reasonable layout wiring and grounding is firstly resolved in design of EMC for PCB with high-speed and digital and analog mixed signals. The fundamental frequency and high frequency harmonic wave, changing speed of signals, distributing parameters of the circuit, conducting coupling, radiate coupling, radiating of unsuited wires and mix disturbances was analyzed. The Layout-wiring was put up according to of layers PCB, plane of power supply, the layout and wiring rules of clock circuit and high frequency circuit, Grounding by one spot or more spots was selected. |
