Abstract
Circuits, methods, and apparatus for ordering the timing of clock and data signals. Programmable delay cells are utilized in a data output cell to control a critical multiple data rate input/output write timing so the output can achieve better performance, such as higher maximum frequency of output (Fmax) performance. The delay cells ensure that critical timing criteria between clock signals and data high and low signals are satisfied so that there is a reduced chance of output glitching.
