Abstract
Provided is a grid-type high-speed clock signal distribution network capable of reducing a difference in amplitude of a standing wave on a transmission line and of supplying a signal from any position. The network for transmitting the clock signal is such that ends of the differential signal transmission line are connected via an inductor, a low-amplitude segment is eliminated by a phase shift in the inductor and a standing wave of substantially uniform phase and amplitude is produced, wherein the number of lines connected to the grid point is made the same for entire grid points.
