A microprocessor controlled data recovery unit with an adjustable sampling and signal comparison level. The data recovery unit includes a data channel and a monitor channel. 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 based clock recovery unit in one embodiment, and in another embodiment the clock signal is derived by the microprocessor.
