The Generalized ICN for 25Gbps+ channel using NRZ, PAM-M or Duobinary coding scheme

The integrated crosstalk noise (ICN) has been proposed in the IEEE 802.3ba standard to measure the crosstalk in the high-speed channel and accepted as a replacement of the ICR (Insertion Crosstalk Ratio) for channel noise estimation. As the PHY options of NRZ, PAM-4 and/or Duobinary are actively explored for higher data rate, a generalized ICN model will be needed for characterizing the channel SI performance. This paper presents the analysis of the integrated crosstalk noise (ICN) model for 10 Gb/s NRZ coding based system and generalizes the ICN model for 25 Gb/s and beyond system adopting the NRZ, PAM-4 or Duobinary coding scheme.
