Abstract

A cell site device and an associated clock synchronization method are provided. The cell site device includes a clock synchronizer, a first processing circuit, and a second processing circuit. The clock synchronizer generates a first operation clock and a second operation clock. The first operation clock and the second operation clock have a specific synchronous relationship, and the clock synchronizer is adjusted by a synchronizer setting signal. The first processing circuit generates the synchronizer setting signal according to one of an external clock synchronization source and an internal clock signal. The clock synchronizer respectively transmits the first operation clock and the second operation clock to the first processing circuit and the second processing circuit. The first processing circuit generates a cross-unit periodic synchronization signal and transmits the cross-unit periodic synchronization signal to the second processing circuit.
