Abstract

A seamless clock distribution scheme for a system incorporating sequential digital logic devices disposed on multiple parallel boards for reducing or substantially eliminating skew. The multiple parallel boards are positioned on and project outward from one side of a centerplane. A single clock board, generating multiple copies of the system clock and mounted at a right angle to the parallel boards on the opposite side of the centerplane are connected by shared pins passing through apertures formed in the centerplane. This shared pin connection allows for simple, though near-ideal transmission of the clock signal copies between the parallel logic boards and the clock board with a minimum mismatch of the clock signal between two parallel boards.
