PURPOSE: A synthesizer for a mobile communication base station is provided to reduce the number of the entire signal line by transmitting control data for generating a local frequency, through one data line. CONSTITUTION: A connector(141) interfaces data transmitted from an RF(Radio Frequency) control card assembly(130) through one data line, through one port. A ROM(142) outputs data for generating a local frequency, an enable signal, and a clock signal, according to the data interfaced in the connector(141). A PLL(Phase Locked Loop)(143) is operated according to the enable signal outputted from the ROM(142), and is synchronized to the clock signal, for generating the local frequency corresponding to the data. |
