Abstract
In a high speed synchronizing circuit, the rising edge of an asynchronous input signal is used to set an input RS flip-flop. First and second latch registers monitor the input RS flip-flop. Each latch register generates a reset signal before a change in the logic level of the system clock for resetting the input RS flip-flop. The reset pulses are very narrow which enables the RS flip-flop to be quickly conditioned to receive the next asynchronous signal.
