Abstract:
A technique for indicating an input cable length includes measuring within a cable equalizer circuit a differential voltage that varies approximately linearly in proportion to cable length. The measured voltage is translated into a cable length measurement corresponding to the connected input cable. The translated input cable length measurements can be provided on a graphical user interface (GUI) in the form of a graphical representation and/or numerical value.
