ABSTRACT:
A programmable, timing signal generator propagates a digital wave along a delay chain comprised of series connected inverters that has sufficient stages that the edge of the wave will not propagate to the end during one system clock cycle time. The delay chain is sampled once each clock cycle, and the point to which the wave has progressed is encoded. Programmable, fine leading and fine trailing edge registers store, as a fraction of the clock cycle time, the desired locations of the timing signal leading and trailing edge relative to the clock edges.
