    • In a network environment, a first master timing generator generates a first frame reference signal and a second master timing generator generates a second frame reference signal. A first data source generates a first data source signal, a first frame source signal, and a first clock source signal in response to a selected one of the first and second frame reference signals. Similarly, a second data source generates a second data source signal, a second frame source signal, and a second clock source signal in response to a selected one of the first and second frame reference signals. A timing recovery circuit generates a recovered reference signal and a recovered clock signal in response to a selected one of the first and second frame reference signals. A phase aligner stores the first data source signal in response to the first frame source signal and the first clock source signal. The phase aligner also stores the second data source signal in response to the second frame source signal and the second clock source signal. The phase aligner aligns a phase of the first data source signal with a phase of the second data source signal in response to the recovered reference signal and the recovered clock signal.
    • 在网络环境中,第一主定时发生器产生第一帧参考信号,而第二主定时发生器产生第二帧参考信号。 响应于所选择的第一和第二帧参考信号之一,第一数据源产生第一数据源信号,第一帧源信号和第一时钟源信号。 类似地,第二数据源响应于所选择的第一和第二帧参考信号之一产生第二数据源信号,第二帧源信号和第二时钟源信号。 定时恢复电路响应于所选择的第一和第二帧参考信号之一产生恢复的参考信号和恢复的时钟信号。 相位对准器响应于第一帧源信号和第一时钟源信号而存储第一数据源信号。 响应于第二帧源信号和第二时钟源信号,相位对准器还存储第二数据源信号。 响应于恢复的参考信号和恢复的时钟信号,相位对准器使第一数据源信号的相位与第二数据源信号的相位对准。
