Title: Interface circuit for data transmission and method thereof

Abstract: An interface circuit for data transmission and the method thereof is described. The interface circuit includes a transmitter providing data through first data signals during the data periods corresponding to rising and falling edges of a clock signal, a transition detection unit selectively asserting a detection signal in response to the number of the first data signals having transitions between every two adjacent data periods, a transition reduction unit generating second data signals by outputting the inverted and non-inverted first data signals respectively when the detection signal is asserted and de-asserted, and a receiver restoring the data from the second data signals and the detection signal.
