A system clock synchronization apparatus, for use in a mobile communication system, supplies a GPS clock received from a GPS reception module to a Radio Frequency clock generation module and selects a candidate system clock. The candidate system clock is selected from among plural candidate system clocks having different phases, which can be most stably synchronized with a reference synchronization time signal as the final system clock. The apparatus includes a Global Positioning System reception module; a Radio Frequency clock generation module that generates a system reference clock and outputs an RF clock generated by synchronizing the system reference clock to the GPS clock in phase; and a system clock generation module that generates multiple candidate system clocks having different phases using the RF clock and selects one of the candidate system clocks which generates in a range of an enable duration of the reference synchronization time signal. |
