$37.75
10-3-2019 UPDATE: - Blanking signal (SCART P16) has been connected to satisfy SCART TV’s in PAL territory.
CORRECTION - ONLY 1 UX60-MB-598 IS REQUIRED. NOT 2 AS THE COMPONENT MAP SUGGESTS!!
See ZIP file for license, readme & component map/BOM
If the cost of production is too expensive, please download the Gerbers and take them elsewhere.
My Champions,
This is something that I put together a long time ago, but never had the time to support, therefore, it hasn’t been released. Until now! I’m giving the Double Penetration SD away to the community, absolutely for free. This is “fairly” well polished. There were a couple of things that I wanted to do a little differently, but from an analog video perspective, this is 100% rock solid. This isn’t “polished” enough by my own standards to sell in production, but it’s a fine enthusiast project with fairly sound engineering.
Here are a couple of things to note:
There are two different clamping elements for the sync input.
The sync output that is driven into the DVI (capture card) is always shaped to a logic level, there’s nothing that you need to do. Regardless if the system you’re pairing this device with is using CVBS, LUMA, 75Ω C-Sync or even TTL C-Sync. Everything should get along, just fine.
The sync output that is driven into the SCART-F output is NOT shaped to logic level, but is buffered via the 4th channel of the 7374 and is termination ready & friendly for all consumer grade devices. This means that you get the benefit of 100% compatibility with your Datapath capture, all while having an untampered with sync-signal that’s driving into your monitor or capture-card on the SCART output.
I’ve designed this so that SDTV component video is 100% compliant and supported. If you want to use component cables, just buy an RCA to SCART plug adapter and stick it into the SCART input, it will work just fine and the Datapath will not give you any trouble. https://goo.gl/DjjnSN
The component map attached is fairly self-explanatory. Try to use 5% resistors. The 2 1206 4.7uF caps by the USB port I accidentally rotated in the wrong direction, hence the lines through the footprints to show the proper orientation. This is the DVI connector that I like to use is: https://goo.gl/F9ti8Q - The 3 lug switch is generic, and should accommodate most types. On the 4 corners of the board, I have milled out M3 sized stand-offs. You can use stand-offs, or even make a little case for this thing if you’d like. Also, OSHPARK has difficult with cutting slots. The milled ports that the SCART connector’s supposed to fit into, make sure whatever board-house you use understands that those should be fully routed out.
Well, that about does it. I hope someone can get some good use out of this.
