The LT6555 is a complete 3-channel wideband video 2:1 multiplexer with internally set gain of two. This part is ideal as an output port driver for HD component or high-resolution RGB video products. The basic application circuit is shown here with terminations shown on all ports, though in many applications the input loading may not be required. One thing this diagram does not reflect is the convenient flow-through pin assignments of the part, in which no video traces need cross in the printed-circuit layout. This maximizes isolation between channels and sources for best picture quality.
