Abstract: An IO method and system for bit-deskewing are described. Embodiment includes a computer system with multiple components that transfer data among them. In one embodiment, a system component receives a forward strobe signal and multiple data bit signals from a transmitting component. The receiving component includes a forward strobe clock recovery circuit configurable to align a forward strobe sampling clock so as to improve sampling accuracy. The receiving component further includes at least one data bit clock recovery circuit configurable to align a data bit sampling clock so as to improve sampling accuracy, and to receive a signal from the forward strobe clock recovery circuit that causes the data bit sampling clock to track the forward strobe sampling clock during system operation.
