Abstract:
1. A method of calibrating a differential receiver having first and second inputs, comprising: placing the first and second inputs at the same voltage; examining an output of the differential receiver over a period of time; determining from the examination if the differential receiver has an offset; compensating for the offset by applying an offset cancellation to the differential receiver; after said compensating for the offset, capturing data, at least in part, using the differential receiver; detecting lane-to-lane skew between frames of data, including the data captured during said capturing data; and using the detected lane-to-lane skew to alter a manner in which captured data are processed to achieve lock by adjusting a timing of each frame relative to another of the frames over a range that is less than one unit interval in duration to achieve bit lock between the frames.
