Abstract:
In this paper, the TDR impedance and eye diagram of the 56G PAM4 system are simulated and measured through a practical case, and the accuracy of less than 5% is finally obtained. Several key factors affecting the accuracy of simulation and testing are discussed in detail, which will be guiding significance for the 112G and 224G serdes system SI simulation work.
