Abstract
A method and apparatus for managing transmission of data signals in a plurality of data lines. Data signals are received on the data lines and a reference signal. On each of the data lines, a delay between the data signal and the reference signal is measured to form a plurality of delay measurements. A set of delay values from the delay measurements is generated. In a preferred embodiment of the present invention, the delay values are selected to equalize the delay in each of the data lines to have the same delay as the data line having the longest delay. The delay values are used to adjust delay in a transmission in each of the plurality of data signals in the data lines. In the preferred embodiment of the present invention, the reference signal is set such that transitions for the data signals are centered to the middle of a pulse for the reference signal.
