This article is to propose a PCB design for efficiently eliminating the Simultaneous Switching Noise (SSN) in highspeed digital circuits. The design is proposed by using low-period coplanar electromagnetic band gap (EBG) structure. The design of structure uses the solid plane for the ground and designs an EBG structure plane on the power. This article realizes the simulation of the two EBG structure, and then educes the S parameter curve. The experiment proves that the designing EBG structure can gain sufficient performance in terms of significantly eliminating the SSN. The degree eliminated is, on average, over-50-dB suppression with in over 4GHz frequency range. Compared with the simulation by two EBG structures of PCB board with the same size and the same value of dielectric constant, we find out that if we select the bigger size of the EBG cell, we can gain the lower frequency of stopband. This structure can also inhibit electromagnetic radiation and electromagnetic interference, which is caused by the SSN in the frequency range. The broad-band radiation or EMI suppression performance is also presented in this stopband frequency range. We can improve the quality of the signals through suitable components placement and layout designs, and adding one more solid ground plane above the EBG power plane.
