Clock Distribution Networks

[technoguy]

In a synchronous digital system, the clock signal is used to define a time reference for the movement of data within that system. The clock distribution network distributes the clock signal(s) from a common point to all the elements that need it. Since this function is vital to the operation of a synchronous system, much attention has been given to the characteristics of these clock signals and the electrical networks used in their distribution. Clock signals are often regarded as simple control signals; however, these signals have some very special characteristics and attributes.
