The voltage waveforms at the two ends of a wire or transmission line are normally different. • There is time delay from one end of a wire or transmission line to the other. • The power distribution system has many defects that can compromise performance. • IC packages have unwanted parasitics, mainly inductances, that can degrade performance • Driver outputs are not ideal. They have limits, such as finite, non-zero, rise and fall time and a non-zero output impedance. • Signal inputs are not ideal.
In digital circuits, there are so many signal paths that function as transmission lines that it is not possible to achieve precision impedance matching on all of them. As a result, logic circuits are designed such that there is a tolerance for impedance mismatching. This tolerance does not allow for arbitrarily large amounts of mismatch. Therefore, it is necessary to invoke a level of impedance matching that is adequate for proper operation. One of the problems this creates in a design is to know how much tolerance for impedance mismatching a logic family has and insure that the design rules maintain this level of precision.
They are formed by etching precise shapes in the copper foil of the outer layer of the PCB. The frequency at which these functions are executed is directly dependent on how accurately they are etched. In a digital PCB, these functions will be performed by discreet components so this kind of feature accuracy is not required. What is needed in a digital PCB is accurate trace width and dielectric thickness control in order to insure that transmission line impedances are kept within allowable tolerances.
