DIFFERENTIAL DATA TRANSMITTING/RECEIVING DEVICE AND DIFFERENTIAL DATA TRANSMITTING/RECEIVING METHOD UTILIZING 3-LEVEL VOLTAGE

摘要

PROBLEM TO BE SOLVED: To provide a differential data transmitting/receiving device and a differential data transmitting/receiving method, which can improve a transmission efficiency.;SOLUTION: In the differential data transmitting/receiving device and the differential data transmitting/receiving method, three pieces of data can be transmitted simultaneously using two sets of transmission lines, that is, four transmission lines. In a differential data transmitting/receiving device and a differential data transmitting/receiving method in a preferable embodiment, either one of two transmission lines in one transmission line set is controlled to an intermediate level voltage, and the other transmission line therein is controlled to a high- or low-level voltage. As a result, the two transmission lines in one set of transmission lines are controlled so as to keep a voltage level having a constant difference. A first divided voltage DC1 and a second divided voltage DC2 for generating reference transmission data can also have a voltage difference level which is kept constant. Thus, the differential data transmitting/receiving device and the differential data transmitting/receiving method have operational characteristics improved upon data transmission.;COPYRIGHT: (C)2011,JPO&INPIT
