Automotive Applications

To minimize cost they want to use just two wires, either a coaxial cable, a twisted pair or a shielded twisted pair. They want an asymmetric standard; high bandwidth video goes in one direction, low bandwidth control signals go in the other direction, sometimes control goes in both directions. They also want the option to send power over the same two wire cable. One problem is that high frequency signals attenuate very rapidly. Doing all of this on a single pair of wires is a miracle of mixed signal engineering. Here are the available solutions to this problem.
