Abstract

See full text

A series clock deskewing apparatus uses a series terminated single transmission line system to deliver a clock signal to a load. A plurality of series clock deskewing apparatuses are implemented, one for each load, so that the clock signal is delivered to all loads simultaneously. Each series clock deskewing apparatus has a single series termination resistor with the same impedance value as the transmission line to which it is coupled. For each load, the clock signal travels the transmission line from a clock generator to the load and is simultaneously applied to the deskewing apparatus. A clock signal is reflected at the load back to the deskewing apparatus. The roundtrip transit time is determined by the deskewing apparatus which causes an appropriate delay to adjust each clock signal to arrive synchronously at all the loads. A programmable output driver impedance network can be used for the single line termination resistor of the series terminated clock deskewing apparatus can be used with transmission lines having different line impedances.
