Analysis of Crosstalk Noise for Coupled Microstrip Interconnect Models in High-Speed PCB Design

In high-speed regime, as the PCBs (Printed Circuit Boards) are diminished, and the continuous increasing of the clock frequency in the state-of-the-art digital systems, at higher frequencies there is no more interconnects are transparent. The behavior of the electrical properties of traces (Transmission lines) plays a major role in determining the performance of the PCB board. As an enormous increase of frequencies and usage of data rates and decreasing of size, it's necessary to check the signal integrity issues on a PCBs to reduce failure products. In this paper, we design and analyzed the coupled transmission lines for a single-ended micro-strip model with 50Ω characteristic impedance and extracted RLC parameters. Estimated the Near End Crosstalk(NEXT) and Far End Crosstalk (FEXT) noise in ADS and validated with SPICE Tool on victim line and also, compared with an empirical equations values.
