Abstract
A system and methods are provided for switching a signal from a first transmission media having a characteristic impedance to a second transmission media. The system includes a driver for driving a signal, the driver having a driver input having a high impedance relative to a characteristic impedance of the first transmission media and the driver having a driver output having an impedance equal to the characteristic impedance of the first transmission media. A first switch couples the driver output either to the first transmission media or to the second transmission media and couples a signal from the first transmission media, which is coupled to the driver input, either to the first transmission media or to the second transmission media. A first switch controller controls the first switch to either simultaneously couple the driver output to the first transmission media and the signal from the first transmission media coupled to the driver input to the second transmission media or simultaneously coupling the driver output to the second transmission media and the signal from the first transmission media coupled to the driver input to the first transmission media. A terminator having an impedance equal to the characteristic impedance of the first transmission media for terminating a signal from either the first or the second transmission media is switched by a second switch to terminate either the first or second transmission media.
