English Amiga Board - View Single Post - Amiga RGB to S-Video + composite adaptor

@tigrr: There is a zip file containing an Eagle project linked from one of my earlier posts in this thread. The AD725 can be used with some modification, as it does not have the same pinout. It also requires a different clock crystal (4x higher). I didn't think the luma trap was worth it, since there is a high quality s-video output available. Also, my original design was NTSC only, so I was able to leave out the clock crystal and use the clock from the Amiga (not possible with AD725).

@Zetro: I've already filled my cart at Newark with ~$8 work of parts. If you want to do a combined order, PM me a list of Newark part numbers for the stuff you want. Here's some stuff I bought for the video encoder:

AD724JRZ
4.43MHz Crystal
20pF Capacitor

I had to buy a 100-pack of 75-ohm resistors, so don't bother looking that up. I'll just give you some.
