    • A serial-to-parallel converter (130) samples serial data DA1 comprising a first data string, which includes one or more unit data strings each including a predetermined number of bits (00XXX . . . XXX) and which is input after a synchronization period, in accordance with a clock signal CL1 which has been used to generate the serial data by converting original parallel data into serial form, thereby converting the serial data to parallel data from one unit data string to another. Signal generation means (140) generates a synchronization signal corresponding to a synchronization period in accordance with the serial data DA1 and the clock signal CL1. The serial data includes a second data string (1100 . . . 000) which appears in each synchronization period and which includes one or more unit data strings having a predetermined bit pattern. If the signal generation means (140) detects a unit data string (11000 . . . 000) in the second data string, it generates a synchronization signal. In accordance with the synchronization signal, the serial-to-parallel converter (130) detects the start position of the unit data string in the first data string.
    • 串行到并行转换器(130)对包括第一数据串的串行数据DA1进行采样,该第一数据串包括一个或多个单元数据串,每个单元数据串包括预定数量的位(00XXX ... XXX),并且在同步周期 根据已经用于通过将原始并行数据转换为串行形式来生成串行数据的时钟信号CL1,从而将串行数据从一个单元数据串转换成另一个单元数据串。 信号产生装置(140)根据串行数据DA1和时钟信号CL1产生与同步周期对应的同步信号。 串行数据包括出现在每个同步周期中并且包括具有预定位模式的一个或多个单元数据串的第二数据串(1100 ... 000)。 如果信号产生装置(140)检测第二数据串中的单位数据串(11000.000),则产生同步信号。 根据同步信号,串并转换器(130)检测第一数据串中的单位数据串的起始位置。
