What is a Clock Tree?

A clock tree distributes timing signals within a system and includes clocking circuitry and devices. Since systems often have several ICs with different clock performance requirements and frequencies, a "clock tree" refers to the multiple clocks required to meet the system's needs. Clock tree complexity depends on the system's requirements. A single reference clock is sometimes cascaded and synthesized into many different output clocks, resulting in a diagram that looks a bit like a sideways tree.
