ABSTRACT:
A clock changeover device comprising a first input port for accepting a first external clock signal, a second input port for accepting a second external clock signal, and an output port for outputting a selected one of the clock signals. The clock changeover device also comprises a circuit for generating a control signal as a function of one of the external clock signals. The control signal has a first state and a second state, the control signal being at the second state when the second external clock signal is coupled to the second input port, the control signal being at the first state when the second external clock signal is not coupled to the second input port. The clock changeover device further comprises an output circuit responsive to the control signal for coupling the first input port to the output port when the control signal is in the first state and for coupling the second input port to the output port when the control signal is in the second state.
