    • An apparatus and a method for frequency locking are provided. The apparatus includes a phase-locked loop (PLL), a local clock generator, a data buffer unit and a control unit. The PLL locks the phase and the frequency of a radio frequency signal to generate a recovery clock signal and received data. The data buffer unit writes the received data into an elastic buffer of the data buffer unit according to the frequency of the recovery clock signal, and reads the received data from the elastic buffer according to the frequency of a local clock signal generated by the local clock generator. The control unit obtains a write-in address and a read-out address in the elastic buffer, and sends a control signal to the local clock generator for adjusting the frequency of the local clock signal according to relationship between the write-in address and the read-out address.
    • 提供一种用于频率锁定的装置和方法。 该装置包括锁相环(PLL),本地时钟发生器,数据缓冲器单元和控制单元。 PLL锁定射频信号的相位和频率以产生恢复时钟信号和接收的数据。 数据缓冲器单元根据恢复时钟信号的频率将接收到的数据写入数据缓冲器单元的弹性缓冲器,并根据由本地时钟产生的本地时钟信号的频率从弹性缓冲器读取接收的数据 发电机。 控制单元在弹性缓冲器中获得写入地址和读出地址,并且根据写入地址和写入地址之间的关系向本地时钟发生器发送控制信号以调整本地时钟信号的频率 读出地址。
