ABSTRACT:
In data communication systems, high speed transceivers are used to transmit and receive signals to and from the communicating medium. These transceivers can transfer data with very high data rates up to 10 mega-bit per second and provide level conversion, signal isolation, ground isolation, and high impedance. To reduce or suppress electromagnetic interference, the square wave signal is translated into a smooth signal which is converted into a signal capable of traveling through the communicating medium. Signal isolation and ground isolation avoid the danger of high voltage shock and damage to the computer equipment from atmospheric disturbances, such as lightning. High impedance provides the bus structure cabling system necessary for multiaccess.
