    摘要: Provided is an apparatus for controlling multiple powers which is capable of turning on and off the multiple powers in their priorities for systems or components to be supplied with the multiple powers such as a liquid crystal display (LCD) module. In the apparatus for controlling multiple powers, an on-signal of high level is applied to an input terminal, and an output of a control signal generating unit is sequentially changed to a high level whenever a clock is applied to a clock signal input terminal by one period, so that outputs of the multiple powers are sequentially output. In addition, an off signal of low level is applied to the input terminal, and an output of the control signal generating unit is changed to a low level in a reversal order whenever a clock is applied to the clock signal input terminal by one period, so that outputs of the multiple powers are interrupted in the reversal order.

    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.
