Abstract :
In VLSI systems, channel bandwidth limitation becomes a crucial problem as the required data rate communication increases, as high-frequency channel loss significantly degrades transmission performance. In this paper, we compare non-return-to-zero (NRZ) binary and 4-PAM (pulse amplitude modulation) coding techniques for serial links by fabricating a test board of a micro-strip line. By extracting the micro-strip line parameters, we carry out co-simulations to evaluate spectrally efficient coding for high-speed serial links in terms of signal integrity. We consider the conditions for which multiple-valued signaling provides an advantage over NRZ signaling from the viewpoint of channel profiles.
