How to Model and Simulate 112Gbps PAM4 SerDes Using IBIS-AMI-May 27, 2019 |
With the buildout of 5G wireless networks and the constant demand for bandwidth in cloud-based data centers, serial link data rates continue to skyrocket. The current state-of-the-art serial links use 112Gbps data rates, using PAM4 signaling. PAM4 differs from traditional NRZ signaling in that it transmits 2 bits per symbol, effectively reducing the need for bandwidth by half.
To enter this hot and competitive market, Cadence purchased a startup company in late 2017 called “nusemi Inc.”, and immediately began work on a 112Gbps PAM4 SerDes IP offering.
