    • A data communication device or system includes a preamble unit and a data interface. The preamble unit generates or detects a first preamble having a first length for a first data line, and generates or detects a second preamble having a second length for a second data line. The first length is different from the second length, and data on the first and second data lines form parallel data. The data interface communicates a first data with the first preamble via the first data line and communicates a second data with the second preamble via the second data line. The respective length and/or respective pattern of each preamble are adjustable and/or programmable.
    • 数据通信设备或系统包括前同步码单元和数据接口。 前导码单元产生或检测具有第一数据线的第一长度的第一前同步码,并且生成或检测第二数据线具有第二长度的第二前同步码。 第一长度与第二长度不同,第一和第二数据线上的数据形成并行数据。 所述数据接口经由所述第一数据线与所述第一前同步码传送第一数据,并经由所述第二数据线与所述第二前同步码传送第二数据。 每个前导码的相应长度和/或相应模式是可调节的和/或可编程的。
