CROSSTALK ANALYSIS FOR HIGH-SPEED PULSE-PROPAGATION IN LOSSY ELECTRICAL INTERCONNECTIONS

The effects of interconnection loss (both dc loss and skin effect loss ) on crosstalk noise for a coupled lossy interconnection system, with various termination conditions, coupled lengths, spacings, and interco nnection structures (microstrip lines versus strip lines) are investig ated. Fourier transform techniques and numerical methods are applied t o solve the coupled transmission line equations for the strong couplin g case (mutual coupling between the active line and the quiet line). T he interconnection is either terminated by its approximated matched lo ad impedance, R(o), or by the equivalent loading capacitance of the re ceiver, C(L). General design guidelines for controlling the crosstalk noise and reflection noise in lossy interconnections are discussed.
