Modeling of Crosstalk in Transmission Lines High-speed Digital Devices

Work concerns a direction electromagnetic the compatibility (EMC) which performance of requirements leans against correct designing of means. Importance of an estimation of crosstalk which arise between conductors in printed circuit board and cable lines is proved. Questions of construction of model for an estimation of crosstalk and an estimation of capacitor and inductive parameters of spending structures, the account of properties of materials of conductors and dielectric, printed-circuit boards applied to the bases and isolation of conductors are considered. Theoretical bases of crosstalk and questions of construction of their mathematical models are considered. Specification of models of lines the transfers necessary for calculation of crosstalk is resulted. The electric capacity as the base parameter which knowledge allows to calculate all key parameters necessary for an estimation of crosstalk is allocated. Results of the analysis of possible methods of calculation of electrostatic capacity in equipment designs, including analytical and numerical, and also mathematical models which can be used at designing of printed-circuit boards and cable connections are resulted. In a final part researches are summed up, conclusions, practical recommendations contain.
