  • Retiming circuit for pulse signals, particularly for microprocessor peripherals
    Patent number: 4811282
    Abstract: A digital retiming circuit for synchronizing a pulse signal with a local clock aligns incoming pulse signals with the local clock using a fully digital technique. The incoming signal is stored in a storage circuit which is disabled until the pulse signal has gone low before rising again. The output of the storage circuit is used to trigger a flip-flop, whose output is converted into a signal aligned with the local clock by means of a cascade of inverters and transfer gates enabled by the local clock. A trigger circuit resets the flip-flop in step with the clock whenever the incoming pulse signal is low.
