1.4. Summary

A typical end-to-end transceiver link is comprised of three main components:

  • PCB material
  • Stack-up design
  • Channel design

High-speed channel design involves understanding the first-order factors that impact performance in each one of those components. These first-order factors are:

  • Signal attenuation
  • Discontinuities and impedance control
  • Crosstalk

Some recommended design choices to oppose those effects are summarized below.
