Abstract: PURPOSE: An output buffer controlling circuit is provided which controls an output buffer to be in disable state in case of initial power-up of an SDRAM to prevent unnecessary current consumption before generation of inner voltage. CONSTITUTION: An output buffer controlling circuit includes an inner voltage generator(100), an inner voltage detector(110), an external voltage detector(120), an output buffer reset unit(130), a level shifter(140) and an output buffer(150). The inner voltage generator receives an external voltage to generate an inner voltage. The inner voltage detector accepts the inner voltage to detect generation of the inner voltage to generate an inner voltage detection signal. The external voltage detector detects generation of the external voltage to generate an external voltage detection signal. The output buffer reset unit receives the inner voltage detection signal and a read signal to initialize an output. The level shifter judges if the inner voltage is normally applied using the inner voltage detection signal and the external voltage detection signal to increase an n-bit output enable signal having the inner voltage level to the external voltage level. The output buffer buffers the n-bit output control signal of the level shifter with the external voltage level to generate an n-bit output signal.

Abstract: PURPOSE: A channel RF controller using a DLL macro in a CDMA system is provided to offer a channel RF controller using a DLL macro in a CDMA system generating and distributing clocks without using a PLL(Phase Locked Loop) element. CONSTITUTION: If a detector(202) in a channel RF controller in a CDMA base station sets up a port to receive a clock, the first receiver(201) receives a chipx8 clock from a BTMA(BTS Timing Management board Assembly) and transmits this clock to an STM(System Timing Module)(203). At this moment, the detector(202) transmits a received Even_sec to the STM(203). The STM(203), receiving the clock, executes a DLL macro in an internal DLL processing part(204) to convert the transferred chipx8 clock into a chipx16 clock. Then the STM(203) uses the generated chipx16 clock and the Even_sec for board internal processing. In order to transmit and process CDMA data, the STM(203) transmits the chipx16 clock and the Even_sec to a load part(206) through the first driver(205). The first driver(205) transmits the chipx16 clock and the Even_sec to the second receiver(208) of an RCPA after feeding them back. In other words, the transmitted chipx16 clock is transferred to the STM(203). The DLL processing part(204) of the STM(203) executes the DLL macro, converts the chipx16 clock into a chipx16 clock, a chipx24 clock and a chipx32 clock, and then transmits them to the second driver(209). Meantime, the Even_sec is transmitted to the second driver(209) from the second receiver(208).
