    Abstract: A microprocessor (45) controlled data recovery unit with an adjustable sampling and signal comparison level. The data recovery unit includes a data channel (47a) and a monitor channel (47b). The monitor channel samples an incoming data stream in a varying manner. The results of the sampling in the monitor channel are used to adjust the sampling and comparing of the signal in the data channel. The data recovery unit includes a PLL (35) based clock recovery unit in one embodiment, and in another embodiment the clock signal is derived by the microprocessor.

    Abstract translation: 微处理器(45)控制数据恢复单元具有可调取样和信号比较级别。 数据恢复单元包括数据通道(47a)和监视通道(47b)。 监视器通道以不同的方式对输入的数据流进行采样。 监视通道中采样的结果用于调整数据通道中信号的采样和比较。 在一个实施例中,数据恢复单元包括基于PLL(35)的时钟恢复单元,在另一实施例中,时钟信号由微处理器导出。
