Abstract
In a described example, a circuit includes a synchronization control circuit having a sync input and a sync control output, in which the sync input is coupled to a sync terminal configured to receive an external clock signal. An internal clock generator circuit has a control input and an output. The control input is coupled to the sync control output. An output circuit has first and second signal inputs, a mode control input and a clock output. The first signal input is coupled to the sync input, and the second signal input of the output circuit is coupled to the output of the internal clock generator circuit. The mode control input is coupled to the sync control output, and the clock output adapted to be coupled to a controller.
