Abstract: A high speed, variable gain video preamplifier circuit disposed on a single IC which can accommodate multiple video input channels supplied by cables of varying length. A multiplexer 34 uses information about the cable length supplied to input pads to selectively connect the outputs of several series connected compensating amplifiers 42(a-b), 44 and 46 to the variable gain amplifier 36. The preamplifier circuit is characterized by a comparative wide common mode input range, as well as being capable of accepting two input channels and providing efficient cable compensation.
