Abstract
A method, computer readable medium, system and apparatus that acquires data link timing includes sequentially introducing a delay and sampling data on a link after each sequentially introduced delay. A starting edge of a valid data eye and a trailing edge of the valid data eye during the sequentially introducing the delay and the sampling of the data is determined. The sequentially introduced delay when the starting edge of the valid data eye is detected and a subsequently introduced delay when the trailing edge of the valid data eye is detected are recorded. A bit sampling time that provides the timing for the sampling of data in the valid data eye between the sequentially introduced delay and the subsequently introduced delay is determined. By way of example, an optimum bit sampling time is determined as a mean from the transition of the starting edge of the valid data eye to the trailing edge of the valid data eye. The bit sampling time for the sampling of data is applied and the link is established.
