HIGH SPEED DATA TRANSMISSION AND RECEPTION SYSTEM AND METHOD FOR REMOVING SIMULTANEOUS SWITCHING NOISE AND INTERFERENCE

摘要

Disclosed are a high speed data transmission and reception system and method which are capable of removing a simultaneous switching noise and ISI at low cost while using a small amount of area. A transmitter used in the data transmission and reception system includes: a data mapping unit which maps two-bit input data to one of the pieces of code, wherein the voltage level of a first signal line, the voltage level of a second signal line, and the voltage level of a third signal line are set in each of the pieces of code; and a transmission driver which outputs data corresponding to the input data through the first signal line, the second signal line, and the third signal line having voltage levels corresponding to the piece of code mapped. Here, each of the voltage levels are '+1', '0' or '-1', and the number of signal lines having a voltage level of '+1' is identical to the number of signal lines having a voltage level of '-1'.
