A data transmission system with a reduced power consumption, a method and transmission circuit

摘要

A data transmission system, comprising:an encoder (400, 905),a transmitter (105, 910),a transmission line (115, 915),a receiver (920), anda decoder (300, 925),the encoder (400, 905) which converts data words supplied in the code words,wherein the transmitter (105, 910) coupled to the encoder and with the transmission line (115, 915) is connected to the code words on the transmission line (115, 915) to be fed,wherein the receiver (920) with the transmission line (115, 915) is connected to the code words on the transmission line (115, 915), andthe decoder (300, 925) is coupled to the receiver, in order to the detected code words in the data words to feed convert,characterized in thatthe transmission line (115, 915) asymmetrically over a termination (110) with a high voltage potential (vhigh) is completed and the transmitter (105, 910) a pull - down - driver (105), which is designed, the voltage on the transmission line to a low voltage potential to draw,wherein the high voltage potential on the transmission line to the binary value one, and the low voltage potential on the transmission line represents the binary value zero,andthe encoder (400, 905) in the code word the binary values of the bits of the supplied data word inverted when the number of binary values zero in the data word is greater than half the number of bits in the data word, and otherwise, the binary values of the bits of the supplied data word.
