ABSTRACT:
A pulse generator for generating an output pulse which is synchronized to an internal clock pulse includes a detector latch circuit (24), a master latch (12), a clocked latch (14), a first clocked half-latch (16), and an output logic circuit (18). Th detector latch (24) is responsive only to the positive edge of the asynchronous pulse of a varying width for generating a trigger signal which is latched to a low logic level. The master latch (12) is responsive to the trigger signal for generating a first latched signal which is latched to a high logic level. The clocked latch means (14) is responsive to the first latched signal and a first internal clock pulse signal for generating a second latched signal which is latched to a high logic level. The first clocked half-latch (16) is responsive to the second latched signal and a second internal clock pulse signal for generating a control signal. The output logic circuit (18) is responsive to the first internal clock pulse signal and the control signal for generating an output pulse signal which is synchronized to the first internal clock pulse signal when the control signal is at a low logic level. A clearing circuit (19) is provided and is responsive to the control signal and the first internal clock pulse signal for generating a clearing signal which resets the first latched signal to a low logic level at the output of the master latch.
