Abstract
Methods and systems are disclosed for reduced coupling between digital signal lines. For disclosed embodiments, return-to-zero signaling is dynamically blocked so that high logic levels remain high through entire clock cycles where the next data to be output is also at high logic levels. The dynamically blocked return-to-zero signaling reduces capacitive coupling between digital signal lines, such as clock and data signal lines, that are in close proximity to each other by reducing current flow that would otherwise occur with return-to-zero signaling. The dynamically blocked return-to-zero signaling can be used in a wide variety of environments and implementations.
