Abstract
A frame reference signal is produced as a function of a clock signal. A first timing generator generates a coarse timing signal having a nominal period and a transition occurring at a precise temporal position with respect to the nominal period. The nominal period is a function of the frame reference signal. The temporal position is a function of a first input timing command and the clock signal. A second timing generator generates at least one fine timing transition as a function of a second input timing command and the clock signal. A combiner circuit uses the coarse timing signal to select one of the at least one fine timing transitions to output a precise timing signal, wherein the precise timing signal has a high temporal precision with respect to the frame reference signal.
