7.2.1 Video Performance

The LMH6574 has been designed to provide excellent performance with production quality video signals in a wide variety of formats such as HDTV and High Resolution VGA. Best performance will be obtained with back-terminated loads. The back termination reduces reflections from the transmission line and effectively masks transmission line and other parasitic capacitances from the amplifier output stage. The Functional Block Diagram shows a typical configuration for driving a 75Ω cable. The output buffer is configured for a gain of 2, so using back terminated loads will give a net gain of 1.
