Abstract 

The performances of ENRZ (Ensemble NRZ) underthe interferences of crosstalk, in conjunction with NRZ (NonReturn-to-Zero), PAM4 (Pulse Amplitude Modulation of 4-level),and PAM3 are investigated. One-side and two-side crosstalk scenarios with varying levels of crosstalk are studied. The simulatedeye-diagram obtained with the four signaling techniques undera range of crosstalk levels are compared and the reasons thatlead to the prominent advantages of ENRZ are analyzed. Asan alternative approach of validating the performances of theunder-study encoding schemes, this research also conducts thealgorithm analysis on the four singling schemes and compares theresults to that previously obtained by the commercial simulationtool. In addition, the study explores the correct method ofadding crosstalk to the ENRZ or other multi-wire based channelswhich is not straightforward due to the neither single-endednor differential nature of the multi-wire encoding system. Anew concept of differential (DIFF)-to-single-ended (SE) crosstalkpenalty is formed and applied to facilitate the theoretical analysis.Different levels of DIFF - SE crosstalk penalty are swept and oneof them is proposed as the recommended crosstalk penalty valuebased on the correlation to the simulated results.
