Hi.
I want design a simple electronic four position vga manual signal switch to feed a vga monitor from 4 (or more) suorces (PCs). Is there someone that can help me?
Hi, Happy123.
Well... I hope this circuit is not expensive as you tell me.
Afterall in my case is necessary switch only rgb signal and hsync vsinc signal.
In a datasheet, for example, I've found a cmos named CD4066. It is a quad solid switch planned for analog signal.
But I have neve used it for this application, so I ask if there is someone thah has experience in this kind of plan.
Hello,
You can find video switcher IC at www.maxim-ic.com. These circuits have integrated video amplifier. I've already built a video switcher for two computers for one monitor. I used maxim's circuits and it's work well.
1.1 RGB: pericom's PI5V331 is good for your application and its cheap **broken link removed**
1.2 Hsync,Vsync,DDC: 4066 or other standard analog switch r O.K.
Hello, hoclv, Mild Seven and Crazyduck.
Thnkyu for your suggestions.
I've already thought about relays, but I need to use a small box for this circuit and a lower power consumption. So I think I'll try to use Max4111 Maxime Ic for rgb signals and Cd4066 for H&V sync.
PI5V331 is a very interesting IC, but seems is not easy find somewere retail.
