A voltage controlled cable equalizer based on the LT1256 video fader is described.
LT1256 videa fader
This design note presents a voltage controlled cable equalizer based on the LT1256 video fader. The circuit features ease of adjustment, simplicity and the capability for remote control. The amount of equalization can be adjusted continuously from the maximum allowed by the passive components to none at all. While the example shows video, this high performance equalizer can be used in any system using long runs of coaxial cable or twisted pair to transmit analog signals.
A voltage or current controlled equalizer is essential in systems which ...
