Summary

This chapter presents advanced topics that draw on the fundamentals of previous chapters. Section 11.1 presents how implementing PAM4 signalling impacts equalization and circuit design. A brief overview of DAC/ADC-based links, also known as DSP-based links, is presented in Section 11.2. A consequence of PAM4 signalling is a smaller vertical eye opening. A digital equalization technique known as “maximum likelihood sequence estimation” is discussed in Section 11.4.
