Next-generation computing and communication systems will handle data streams reaching tens of gigabits per second. Many of them will adopt processors and serializer/deserializer (SERDES) chipsets operating at clock frequencies exceeding the gigahertz range. Traditional parallel bus topologies have reached their bandwidth limits. As parallel buses grow wider, the complexity and cost of printed circuit board (PCB) routing increase exponentially. High-speed serial channels have emerged as a solution to the increasing skew between data and clock lines in parallel bus architectures. The latest serial bus architectures have rapidly replaced traditional parallel bus architectures in high-speed digital systems. Engineers are adopting various gigabit serial interconnect protocols with embedded clocking to simplify wiring and increase the bandwidth per channel.
