Hello All,

I know electronics at a very basic level. And I know what I want to achieve Im just stuck as to how to get there.

What I have is a circuit that converts 23pin commodore amiga video output to 15pin pin VGA connector.

The problem that I am having is that the horizontal video frame is 15.625khz and of course a vga monitor requires 31.5khz signal so I would like to double the frequency of the horizontal sync so that it falls within the correct range.

Can anyone tell me how this can be done preferably very acurately and preferably with a nice IC to make it pretty.

I would realy appreciate some ideas.
