Programmable delay element

A programmable delay element having a fine delay circuit with fractional units of delay. The fine delay circuit has a fine delay circuit with a plurality of selectable delay paths, each delay path having an associated delay interval. The fine delay element is electrically-coupled to a data terminal for receiving and delaying an input signal. A control circuit is electrically-coupled to the fine delay circuit to select the delay path for the input signal. In a further aspect of the invention, the fine delay circuit is electrically-coupled to a coarse delay circuit having a plurality of selectable delay blocks in a repetitive block configuration. The coarse delay circuit is electrically-coupled to a second data terminal for receiving and inserting a second signal through said fine delay circuit. The control circuit is electrically-coupled to the selective delay path of the fine delay circuit and the coarse delay circuit such that either a fine delay, a coarse delay, or a coarse and a fine delay can be selected.
