Note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy. This. circuits makes it possible to connect your VGA card to. For some applications and system. I keep all the rights to this circuit. You can freely build this circuit. VGA to RGB Composite Sync converter. First circuit is for connecting VGA card to video projector or a monitor. VGA card frequencies and has RGB Composite sync input. This. circuit has been succesfully used with Electrohome Projection Systems. ECP 4. 10. 0 data and video projector. This circuit is designed for converting normal VGA signals standard RGB. The circuit is quite simple, because. RGB signal ouput from VGA card is already standard 0. Vpp to 7. 5 ohm load. For sync signals there is a circuit which combines horizonal and vertical. The circuit is simply based. TTL chip with four XOR ports, two resistors and two capacitors. TTL chip ws logical choise because VGA sync signals are TTL level signals. Download Video Motogp Sepang 2013 Full Race more. The sync signal combiner has a system to adjust to different sync polarities. VGA card uses. different sync signal polarities to tell the monitor which resolution is used. This circuit adjusts to sync signal polarity changes in less than 2. VGA monitor in. the display mode change. Analogue composite sync signal converter. First circuit is for connecting VGA card to video projector or a monitor. VGA card frequencies and has RGB Composite sync input. Vpp signal level, 7. This picture is available in GIF and Postscript versions. Note The circuit diagram does not show the wire giving power to IC1. The 5. V power is connected to pin 1. This circuit has been succesfully used with Electrohome Projection Systems ECP 4. VGA and Super. VGA modes. The circuit have been also used succesfully with. Barco video projector using. VGA to TV drivers to get the VGA card to. C1 2. 2 u. F 1. V electrolytic. C2 2. F 1. 0V electrolytic. R1 2. 2 kohm. R2 2. R3 1. 8 kohm. R4 1. R5 2. 7 kohm. U1 7. LS8. 6 or 7. 4HCT8. TTL level sync signal. Many computer monitors have been designed to accept TTL level sync. If you happen to own a monitor which uses TTL level. I have. designed another simpler circuit for monitors which need TTL levels. Note The circuit diagram does not show the wire giving power to IC1. The 5. V power is connected to pin 1. This circuit is basically the same as the first circuit. The only. only difference is that the transistor driver stage have been left. TTL levels signals from the IC are what is wanted. Because. the 7. 4LS8. IC directly drives the output without any further buffering. C1 2. 2 u. F 1. V electrolytic. C2 2. F 1. 0V electrolytic. R1 2. 2 kohm. R2 2. U1 7. 4LS8. 6 or 7. HCT8. 6. Simple sync combining BOX. Sometimes you want to use a ready made BNC cable made for connecting. VGA card to high quality monitor. Those BNC cables have 5 BNC outputs. Signal Function Color in cable. R Red Red. G Green Green. B Blue Blue. HHV HsyncVsync Black. V Vsync White or Gray. Tha cables are usually built should be built from high quality 7. BNC conenctors to guarantee good image quality. You can see a typical schematic of commercial VGA to BNC cable below. This kind of cable can be used with monitors with 5 BNC inputs. But if. you unfortinately have a monitor with RGB and composite sync inputs only. If you cna get. composite sync directly from graphics card, then it is enough to just. HHV connector to the composite sync pinput of the monitor. If you are on unfortunate person who deos not have this kind of graphics. HSYNC and VSYNC. signals to composite sync. You can see this kind of circuit below. C1 2. 2 u. F 1. V electrolytic. C2 2. F 1. 0V electrolytic. R1 2. 2 kohm. R2 2. U1 7. 4LS8. 6 or 7. HCT8. 6. Connecting VGA to Sync on Green monitor. Some monitors use sync on green syncronization instead of separate sync. In that case you cant used my circuits directly. You have to modify those. Sync on Green capability. Generating sync signals to. I have not had any need for such a. I havent designed such option. Check this. article to get the idea what to add to my circuits. For more complete explanation how to deal with sync on green monitors. Sync on Green FAQ. Building the circuit. The circuit is quite simple to built if you have basic skills in. The electronics of the circuits. I used this approach in my prototype. I have designed a circuit board for my VGA to TV converter. Netdisco 2 Download. PCB design. GIF picture scanned at 3. Note that there are some differences in connection of. IC U1 pins in PCB compared to the schematic, but the circuit built to. PCB fuctions in the same way. The circuit need well stabilized power 5. V power source 5. The circuit. takes less than 1. A current, so you dont need a large power supply. If you dont have anythign suitable avalable, you can always use a small. V. voltage regulation circuit. Another option is to take the 5. V power. from PC using methods explained in my How to get power from PC to your circuits document. The wiring should be made carefully and 7. Signals reclections caused by bad.
