Abstract:To resolve the crosstalk problem of the transmission lines in high-speed interconnection system,the properties of the transmission matrix are studied.Both the model of the transmission matrix and the matrix decomposition form are established in the following two cases,one is the crosstalk between the disturbed line and its one adjacent microstrip line on both sides,and the other is the crosstalk between the disturbed line and the two adjacent lines on both sides.The crosstalk cancellation scheme for the above two cases is given,and it is verified with the advanced design system (ADS).The results show that both signal jitter and distortion are greatly improved,the crosstalk is obviously cancelled,and it is illustrated that the crosstalk cancellation effect of the scheme considering two adjacent microstrip lines is better than that of one adjacent microstrip line.It is practical to maintain the integrity of the high-speed signal.
