PCB design for signal integrity

The printed circuit board (PCB) is one of the greatest bottlenecks in implementing high-speed designs. The relatively inexpensive material for volume board designs is slow to change, compared to the rate at which transistor speeds are increasing. Higher speeds are achieved in transistor I/O, while the PCB material and structures see little change, carrying the same bandwidth capabilities used a decade ago and putting a greater burden on the I/O design. The opportunity is at hand to design the best signaling path with today’s current technology and leverage the new capabilities that have come into the PCB industry. This chapter discusses important signal integrity analysis techniques, considerations in ...
