The mechanism of inter-symbol interference(ISI)formation was analyzed in order to analyze the impact of ISI on the high-speed serial systems and performance of different ways of equalization to eliminate ISI.An equivalent circuit model without loss was built according to the transmission line theory and calculation of the probability density function for ISI.An analytic formula of ISI was proposed in the form of equivalent voltage noise.The estimate based on the probability distribution was proved validity compared with the estimate based on the matrix decomposition.By constructing the jitter model of a highspeed serial communication system,the equivalent voltage noise of the system inter-symbol interference in a certain period of time was calculated for different equalization.The effect of mitigating ISI in different equalization manner was compared and a new evaluation indicator for equalization performance was provided.The relationship between the equivalent voltage noise and traditional indicators was discussed,as well as the scope of application.
