AN-1240 Video Transmission Over Twisted Pair Wire (Rev. C)
The circuits in Figure 1 and Figure 2 transmit NTSC video signals over twisted pair wire. They were
designed and tested for transmitting video on inexpensive CAT-3 twisted pair wire. Even when transmitting
on 1000 feet of wire, good quality color video was displayed on a monitor with an NTSC input. Both the
transmit and receive circuits use the LMH6643 dual op-amp that has the proper bandwidth and slew rate
for this application.
