Single-wire synchronous interface

Methods and systems for a single wire synchronization interface are described. A timing device including a first buffer may be connected to a line card including a second buffer. The timing device may control the first buffer to periodically output synchronization pulses to the line card at time intervals. For each output of the synchronization pulse, the timing device may switch the first buffer from the first output mode to the first input mode. In a first input mode, a timing device listens for incoming data on a trace. The line card may periodically receive the synchronization pulse at the time interval. For each reception of the synchronization pulse, the line card may switch the second buffer from the second input mode to the second output mode. In a second output mode, the line card may transmit outgoing data on the trace. 描述了用于单线同步接口的方法和系统。包括第一缓冲器的定时设备可以连接到包括第二缓冲器的线路卡。定时设备可以控制第一缓冲器以时间间隔周期性地向线路卡输出同步脉冲。对于同步脉冲的每个输出，定时设备可以将第一缓冲器从第一输出模式切换到第一输入模式。在第一输入模式下，定时设备侦听迹线上的传入数据。线路卡可以以该时间间隔周期性地接收同步脉冲。对于同步脉冲的每次接收，线路卡
