Abstract

Circuitry for providing an input data signal to other circuitry on an integrated circuit includes a course delay chain and a fine delay chain. These two delay chains are cascadable, if desired, to provide a very wide range of possible amounts of delay which can be finely graded by use of the fine delay chain.
