Abstract :
So far, the only effective way to decrease crosstalk-noise has been to widen space or to put shield trace between traces in PCBs. On the other hand, crosstalk-noise increases as the frequency increases, so that novel approaches to reduce the crosstalk-noise are strongly required in the GHz domain. We have applied a new trace structure “Segmental Transmission Line (STL)” to the crosstalk-noise reduction already and have shown its fundamental effectiveness for the clock signal transmission. In this paper, we apply the STL to reduce crosstalk-noises caused by random data signal in GHz domain and demonstrate that the STL can reduce the crosstalk-noise to about half of it in the uniform-width trace.
