Abstract:

With the development of electronic technology,the first priority for designers is to ensure normal working of high speed circuits.As a signal transmission carrier,the integral transmission of high speed digital signal on PCB board becomes a important indicator of the design.This paper analyzes the reason for and solution of crosstalk by the electromagnetic theory and tests the theory via global and crosstalk simulation of a PCB board.A comparison is made of different termination techniques and the best scheme is selected to decrease crosstalk to a reasonable degree.

Key words: signal integrity;crosstalk;hyperlynx;global simulation
