ABSTRACT:
A skew adjustment circuit employs a novel algorithm enabling a reduction in scale of the circuit of a receiver for a Transition Minimized Differential Signaling (T.M.D.S.) link in accordance with the Digital Visual Interface (DVI) standard. The skew adjustment circuit includes a sampling point selection section that performs comparison processing on oversampled data, assumes transition points of serial data, and outputs a sampling point selection signal; and a data recovery section that outputs oversampled data at the sampling point selected by the selection signal, as sample data for the serial data. Comparison processing is performed on the oversampled data in 4-bit segment units of the serial data, transition point detection signals are held, and the transition points of the serial data are assumed based on those transition point detection signals, when transition point detection signals for at least two segments, which are among the held transition point detection signals, indicate the same result. The comparison processing is performed on pairs of every other point of oversampled data.
