This article describes the Video Line Driver CIRCUIT (LT1206). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:LT1206.

LT1206 is suitable for driving multiple video cables since it has 60MHz bandwidth, 250mA output current capability, and low output impedance. Please keep in mind about unterminated line effect when driving multiple cables. A reflected wave would propagate back to the driver an cause a crosstalk to other lines since the driver output is non zero impedance.

driving video cables circuit schematic

The schematic diagram? shows the LT1206 connected as a distribution amplifier.? To minimize the effect of reflection, each line is separately terminated.? Differential gain and phase performance are also? important and have been considered in the internal design? of the device, especially useful if? the signal is? video composite. Note that at 5MHz the output impedance of LT1206? is only 0.6W, much smaller than the terminating resistor separators.
