NTSC To RGB

[Crazybillybob76]

I'm looking for a chip / Circuit that will take a composite Video signal in and give me a +5/-8V RGB + H&V Sync. Signals out. I'm sure it can be done rather inexpensively (no custom chips), but I'm not sure how!

Hi,

Without custom chips we are talking serious circuits here. You have to take into account frame rates, A/D converters, chroma signals, interlacing etc.

Check out the IC on the first link it may be what you want if not
checkout the last links for thoughts on the subject

I have already looked at the TDA3566A It would be perfect for what I'm doing, problem is Philps Discontinued that chip, and I haven't found a supplier that has them.

On Further searching I've found that every chip listed on these sites is out of production. I agree the single chip is the best Idea, but what are some current run solutions. I'm only looking @ 10-12 units max, so going to a wafer fab. plant for a rerun of discontinued chips is just not realistic in a cost/unit.
I need to plug a VCR/Cam Quarter into a 6" Sharp LQ6RA01 LCD. I've got the LCDs now I need to find out how to connect them.

Hi,

Sorry didn't bother to check if they were still in production. Mind you they still may be in stock in some old dusty shop somewhere.

A quick search, found the TDA3566A listed as a product on the links below. Whether they are still available you might want to email them & check for availabilty, cost & shipping instruction etc.
