Abstract
An apparatus and method for providing a gated output timing signal within a gated clock distribution tree. In accordance with the present invention, a gated clock splitter includes a timing signal input and a combinatorial logic block coupled to the timing signal input that generates a gated timing signal. A gating signal input is coupled to the combinatorial logic block for selectively enabling and disabling the output from the combinatorial logic block. A gate control circuit is coupled to the gating signal input for providing a gate signal to the combinatorial logic block, wherein the gate control circuit provides a full-cycle path for said gate signal to the gating signal input.
