摘要： A wireless modem is mounted to a terminal for wireless communication, and specifically controls an internal drive clock to reduce power consumption in an active mode. The wireless modem includes: a wireless core module for transmitting and receiving a radio signal; a modulator for converting data to be transmitted into a wireless transmission signal and transmitting the converted signal to the wireless core module; a demodulator for converting the signal received from the wireless core module into reception data; a synchronizer for synchronizing the signal received from the wireless core module; and a clock controller for generating a drive clock of each of the modulator, the demodulator, and the synchronizer. A low power clock controller is divided into six main functional blocks of a synchronizer, an analog controller, a modulator, a channel decoder, a demodulator, and a channel encoder, and has a feature that a clock is input only when a main functional block operates. As a result, it is possible to minimize power consumption caused by clock switching when an Orthogonal Frequency Division Multiplexing Access (OFDMA) mobile station modem operates in an active mode through the clock controller.

摘要： In case microcontroller and digital signal processing blocks are used together in one chip, there has been a problem in which the synchronization of the clocks are not consistent with each other when sending a signal from one block to another. In addition, when a reference clock is activated during a change of input signal, an incomplete interval has occurred. Accordingly, in order to solve the above mentioned problem, the present invention discloses a synchronizing circuit which uses a latch circuit("RS") consisted of NAND gates to synchronize an asynchronous input data and a reference clock, thereby solving the problem in which an incomplete interval occurs.
