Needs to be very low power balanced transmission. Distance 50M to 100M
reliable, occupied data rate will be about 12Mbits/sec if synchronous, about
15Mbits/sec async. It does not need to support a lot of the Ethernet
protocol overhead, being used to transmit real time data from high bit rate
sensor. Current approaches are discrete, but I am looking for a packaged
TX/RX soloution to avoid another fully discreet design. Most current high
rate stuff (100M, etc) gulps power quicker than we can supply it! Voltage
levels expected to be +/- 3 to 5V, DC balance scheme by suitable BD encoding
done in software....
