Send Color Video 1000 Feet Over Low Cost Twisted-Pair
Design Note 65
John Wright
It is now possible to send and receive color composite video signals appreciable distances on a low cost
twisted-pair. This technique is similar to the push toward
twisted-pair cables in EtherNet systems to replace
costly coaxial cable connections. The cost advantage of
these techniques is signiп¬Ѓcant. Standard 75О© RG-59/U
coaxial cable costs between 25Вў and 50Вў per foot, but
a PVC twisted-pair is only pennies per foot. This means
hundreds of dollars are saved in installations as short
as 1000 feet, easily paying for additional electronics.
The system also provides for вЂњdropsвЂќ or receiver taps
along the twisted-pair. This bidirectional вЂњvideo busвЂќ consists of the low cost
LTВ®1190 op amp and the LT1193 video difference ampliп¬Ѓer shown in Figure 1. A pair of LT1190s at TRANSMITВ 1,
is used to generate differential signals to drive the line
which is back-terminated in its characteristic impedance.
These ampliп¬Ѓers have high 50mA load driving ability,
while maintaining a very high 450V/Ојs slew rate and
50MHz gain-bandwidth. The twisted-pair receiver is an
LT1193 video difference ampliп¬Ѓer at RECEIVE 1, and it
converts signals from differential to single-ended. The
LT1193 offers features unavailable with other op amp …
