Abstract:
A self-configuring clock interface circuit automatically configures itself according to the type of clock input signals applied to two input terminals interconnected with the interface circuit. The system includes a pair of counters connected to the input terminals and having their outputs connected to the two inputs of an Exclusive NOR gate which acts as a control device for the system. The output of the exclusive NOR gate is coupled to a 2:1 multiplex to control the interconnection of one or the other of two inputs to the multiplex circuit with a clock output for the interface circuit.
