Abstract
A timing generating apparatus includes a master timing module adapted to receive an external reference clock and to generate a coarse timing pulse signal. A slave timing module is coupled electrically to the master timing module and receives the coarse timing pulse signal, from which a fine timing pulse signal is generated. A calibration module coupled electrically to the master timing module and the slave timing module receives the coarse timing pulse signal and the fine timing pulse signal, determines a phase difference value between the two, and generates a phase compensation signal corresponding to difference between the phase difference value and a predetermined phase difference value. The slave timing module includes a delay control unit and a voltage-controlled delay unit, which introduce a phase delay into the coarse timing pulse signal so as to generate the fine timing pulse signal.
