    • PURPOSE: A logic circuit for judging a phase difference between a data and a clock is provided, which knows a phase difference between an input data and a clock automatically, by inserting a logic. CONSTITUTION: When a clock is in a former part of data, the logic circuit generates a low level("0" or PRE_CLKPP) signal if two signals(ADB1_INV,ADA2) have the same data while generating the two signals by reading the input data at a rising or a falling edge. When the clock is in the post part of data, the circuit generates a low level("0" or POST_CLKPP) if two signals(ADB1_INV,ADA1) have the same value at the same phase by reading the input data at a rising or a falling edge. And if the clock is in the former part of data and there is a margin, the circuit generates a low level("0" or PRE_CLK) with the above generated two low level(PRE_CLKPP,POST_CLKPP) signals. And the circuit generates a low level("0" or POST_CLK) with the above generated two low level signals if the clock is in the post part of data and there is a margin.
    • 目的:提供用于判断数据和时钟之间的相位差的逻辑电路,其通过插入逻辑来自动地知道输入数据和时钟之间的相位差。 构成:当时钟处于数据的前一部分时,如果两个信号(ADB1_INV,ADA2)具有相同的数据,则通过读取输入数据产生两个信号,逻辑电路产生低电平(“0”或PRE_CLKPP)信号 在上升或下降的边缘。 当时钟处于数据的后部时,如果两个信号(ADB1_INV,ADA1)在相同相位处具有相同的值,则电路将产生低电平(“0”或POST_CLKPP),通过在上升沿或第 下降边缘 并且如果时钟处于数据的前一部分并且存在余量,则电路产生具有上述产生的两个低电平(PRE_CLKPP,POST_CLKPP)信号的低电平(“0”或PRE_CLK)。 如果时钟位于数据的后部,并且存在余量,则电路产生低电平(“0”或POST_CLK),其中上述产生的两个低电平信号。

    • PURPOSE: Array type signal sampling device and a method thereof are provided to easily perform high-resolution sampling by delaying clock. CONSTITUTION: A plurality of signal sampling modules (100a-100n) is operated by section in a predetermined period. The signal sampling module includes a trigger signal generation unit, a clock phase delay unit, an analog digital converter unit, a sampling data storage unit, and a sampling data output unit. A plurality of signal transmission units (200a-200n) is connected to each of the signal sampling modules and transmits a propagated signal. A plurality of signal reception units (300a-300n) is connected to each of the signal sampling modules and receives a response signal in response to the transmitted propagation signal. The signal transmission unit and signal reception unit are arranged in the widthwise direction when a scan direction of an exploration target is set to the longitudinal direction.
