Abstract:
1. A transmitter circuit for transmitting parallel data, suitable for compensating for influence of crosstalk noise in a pre-emphasis scheme, comprising: first through N first through N first through N first through N wherein the signal modes includes: an even mode in which transition directions of adjoining data are the same; an odd mode in which transition directions of adjoining data are different; and a static mode in which at least one of adjoining data does not transit, wherein the first pre-emphasis circuit section comprises a first pre-emphasis circuit which adds the first data outputted through the first transmission line and an inversion data of the first data having a delay time to the same proportion depending upon a signal mode between the first transmission line and the second transmission line and outputs a first pre-emphasis signal, and wherein the first pre-emphasis circuit section generates the second data output signal by combining the first pre-emphasis signal and the output signal of the second output driving circuit section.
