FREQUENCY SYNTHESIZER CONTROL APPARATUS FOR HOPPING FREQUENCY OF WIRELESS EQUIPMENT AT HOPPING MODE

摘要

PURPOSE: A frequency synthesizer control apparatus for hopping a frequency of wireless equipment at a hopping mode is provided to restrain generation of switching noise by removing a process for reading frequency data from a storage unit and excluding the repeated outputs of same frequency data whenever receiving frame signals. CONSTITUTION: A storage unit(200) stores first frequency data corresponding to a predetermined hopping pattern. A first data management unit(220) reads the first frequency data from the storage unit. A second data management unit(230) reads the second frequency data corresponding to a predetermined frequency value. A data selection unit(250) outputs selectively the first frequency data and the second frequency data according to a predetermined mode selection signal. A data output unit(260) outputs control data corresponding to the selected first frequency data or the selected second frequency data.
