Digital Equalization With ADC-Based Receivers: Two Important Roles Played by Digital Signal Processingin Designing Analog-to-Digital-Converter-Based Wireline Communication Receivers

Wireline input/output (I/O) bandwidth demand within networks in large data centers has increased rapidly over the last decade because of the explosion in data generation from cloud computing, mobile devices, and Internet of Things applications. To support this, both the number of I/O lanes per component and the per-lane data rate have continuously scaled up. For example, Figure 1 shows that the ag...
