Cesar E Alvarez Jr: MOSFET detecting and synchronizing circuit for asynchronous digital data. Teletype Corporation, W K Serp, M Pfeffer, March 8, 1977: US04011465 (20 worldwide citation)

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 SE ...
