ABSTRACT:
An asynchronous data input signal is detected and synchronized by a fast-acting circuit. The input is used to modulate a local clock and a detecting latch is then driven by the data-modulated clock. Most of the propagation delay found in conventional detector-synchronizers is eliminated since the SET input to the latch, which is essentially the clock signal, is generated without any gate delay and the CLEAR input is generated with only a single gate delay. Thus, the circuit is well suited for multiple clock systems in which detection and synchronization to one clock must be accomplished before the pulse of a second clock begins.
