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.
