    • A high frequency bus system (450) which insures uniform arrival times of high fidelity signals to the devices (510), despite the use of the bus (450) on modules (420) and connectors. The high frequency bus system (450) includes a first bus segment having one or more devices (510) connected between a first and second end. The high frequency bus system (450) also includes a second bus segment which has no devices connected to it. The first end of the first segment and the second end of the second segment are coupled in series to form a chain of segments and when two signals are introduced to the first end of the second bus segment at substantially the same time, they arrive at each device (510) connected to the first bus segment at substantially the same time. Conversely when two signals originate at a device (510) substantially at the same time, they arrive at the first end of the second bus segment at substantially the same time. Uniform arrival times hold despite the use of connectors to couple the segments together, despite the segments being located on modules, without the need for stubs, despite the presence of routing turns in the segments and despite the type of information, such as address, data, or control, carried by the signals.
    • 尽管在模块(420)和连接器上使用总线(450),但高频总线系统(450)确保高保真信号到达设备(510)的均匀到达时间。 高频总线系统(450)包括具有连接在第一和第二端之间的一个或多个设备(510)的第一总线段。 高频总线系统(450)还包括没有与其连接的设备的第二总线段。 第一段的第一端和第二段的第二端串联耦合以形成段链段,并且当两个信号基本上被同时引入第二总线段的第一端时,它们到达每一个 设备(510)在大致相同的时间连接到第一总线段。 相反,当两个信号基本上在同一时间发生在设备(510)时,它们在几乎相同的时间到达第二总线段的第一端。 尽管使用连接器将段连接在一起,尽管使用段落位于模块上,但不需要存根,尽管存在段中的路由转换,并且尽管存在信息的类型,例如地址,数据 ,或由信号承载的控制。
