Abstract
By the development of the information superhighway, the current data communication system can be exchanged data quickly and precisely between subscribers. In this paper, LVTTL(Low Voltage Transistor Transistor Logic), Using the fundamental one logic at several kinds of used in communication systems, the LVTTL transmission characteristics were measured by according to the change data transfer rate and the transmission line length. Because the transmission line length required on the current system is 30cm, We analysed LVTTL data transfer characteristics according to the transmission line length required on the current system. The amplitude level of LVTTL at 10Mbps is 3V and 50Mbps is 2.2V and 100Mbps is 2V and 125Mbps is 1.5V and 150Mbps is 1.4V. The length of transmission line 30cm was stable state up to 100Mbps data transfer rate.
