My colleague is an engineer who had worked the sharp prodcut of HC7000 before, he had made a sharp cable of VGA by synchronal cable ,so I will request to him for your requirement .
schematic have got it, but it's a Protel circuit. I can't open it by Orcad tools, I will look for Protel tools and setup it ASAP. Another, "It's a confidential", that engineer said. who hope we don't open it on Web.
