Abstract
A wireless communication apparatus includes an ISDN interface, an RF unit, and a digital phase-lock loop. When synchronization with the digital line has been established, the digital phase-lock loop counts a clock from the RF unit on the basis of the clock of the ISDN, extracted by the ISDN interface and the output of the digital phase-lock loop, and outputs a clock, so that wireless communication is performed in synchronization with the output of the digital phase-lock loop. When synchronization with the digital line has not been established, the digital phase-lock loop frequency-divides the clock from the RF unit in order to generate a synchronization clock for wireless communication.
