    • PURPOSE: A device for parallel transmitting and receiving data is provided to improve a transmitting speed of data by transmitting data with reducing a clock speed as a serial method when data is transmitted. CONSTITUTION: One data line is selected among parallel data lines. To uniform a low and high rate of one selected data line, an original data line is changed by mixing, exclusive-OR, the selected data line and a random signal. A clock is transmitted to an appropriate device for interface by changing the clock with the exclusive-OR of the changed data line and the clock. The data line and the clock transmitted by changing are restored in a receiving side of the device for interface. Thereby the transmitting speed of data is improved by reducing a clock speed than an original clock speed.
    • 目的:提供用于并行发送和接收数据的设备,用于通过在发送数据时以串行方式减少时钟速度发送数据来提高数据的发送速度。 构成:在并行数据线之间选择一条数据线。 为了使一个选定数据线的低速和高速率均匀化,通过混合,异或,所选数据线和随机信号来改变原始数据线。 通过使用改变的数据线和时钟的异或来改变时钟,将时钟发送到适当的设备进行接口。 通过改变传输的数据线和时钟在用于接口的设备的接收侧被恢复。 从而通过减少与原始时钟速度相比的时钟速度来提高数据的传输速度。

    • PURPOSE: A processing method of an encoder signal is provided to precisely control the speed and location of a controlled target by obtaining measurement result including the improved resolution. CONSTITUTION: A sine wave signal of A phase and B phase with 90° phase difference is inputted as the output signal of an encoder sensor part. An analog signal which has a shifted phase is obtained from the sine wave signal on the A phase and the B phase. A comparator converts the sine wave signal of the A phase and B phase and an analog signal which has a phase shifted form into a digital signal, respectively. An eight times multiplied digital signal is obtained from the transformed digital signal. An M/T counter acquires velocity information from the eight times multiplied signal. The location information is obtained from the velocity information. The analog signal which has a shifted phase form is the sine wave signal which has two forms which has a phase shifted at 45° and -45°.

    • PURPOSE: A USB(Universal Serial Bus) transmitter is provided to adjust the crossing point of differential signals transmitted, even after being designed and manufactured. CONSTITUTION: A universal serial bus transmitter is composed of the first and second demultiplexers(111,112), the first and second delay parts(131,132), and the first and second transmitting drivers(151,152). The first demultiplexer(111) receives an input signal(IN) and outputs the first non-delay signal(NDEL1) or the first preliminary delay signal(PDEL1) according to the first control signal(MCON1). The second demultiplexer(112) receives the input signal(IN) and outputs the second non-delay signal(NDEL2) or the second preliminary delay signal(PDEL2) according to the second control signal(MCON2). The first delay part(131) delays the first preliminary delay signal(PDEL1) with a given delay time(TD1) according to the first delay control signal(DCON1) and outputs the first delay signal(SDEL1). The second delay part(132) delays the second preliminary delay signal(PDEL2) with a given delay time(TD2) according to the second delay control signal(DCON2) and outputs the second delay signal(SDEL2). The first transmitting driver(151) receives the first non-delay signal(NDEL1) and the first delay signal(SDEL1) and outputs a positive signal(POS). The second transmitting driver(152) receives the second non-delay signal(NDEL2) and the second delay signal(SDEL2) and outputs a negative signal(NEG).
