Abstract
An apparatus and method for detecting the presence of a valid signal includes an offset generator coupled to a pair of data slicers and an XOR gate. The offset generator is configured to both add and subtract a predetermined voltage to an input voltage in its two outputs. The two outputs of the offset generator are both compared to a predetermined value in a pair of data slicers. If the outputs of the data slicers are the same (i.e., either both offset signals are positive or both are negative), then a valid signal is indicated.
