IBIS-AMI Based Link Analysis of Realistic 56G PAM4 Channels

White Papers

In this paper we report results of IBIS-AMI based link analyses of realistic 56G PAM4 channels. Systems under investigation are represented by channel S-parameters and SerDes AMI models that capture actual chip designs, including impedance, equalizations and embedded tuning. 4-level timedomain input waveforms are processed by Tx and Rx models, which return output waveforms along with sampling times and slicer thresholds. Eye diagram and SER are calculated individually for each eye to measure link performance. Results of upper, center and lower eyes at various data rates are presented. Crosstalk and jitter impacts are investigated.
