PAM4 Signaling

In the realm of high-speed digital PCBs, maintaining pristine Signal Integrity is the defining challenge of modern electronics design. As data rates push from 25G NRZ into the 224G PAM4 frontier, the physical interconnect—the PCB itself—becomes the primary bottleneck in SerDes channel performance. This comprehensive High-Speed Digital PCBs resource provides a physics-to-manufacturing blueprint for engineers…
