Effective use of line termination in high speed logic

As system speed increases, the time available to make signal logic level transitions decreases. The goal is to have a rapid, quiet transition from level to level, making the final signal level available to any receivers at the earliest possible time. One result of this is a very fast signal edge rate which can cause reflection and termination problems in the circuit if the circuit is not properly designed. Looking at high speed logic components, internally the component can have control over the edge rate by how fast the output turns on. Very high speed logic must have a fast turn on rate to achieve fast throughput. The fast turn on/edge rate can cause line reflection problems producing transmission line effects
