The SCART Cleaner is an open-source (CERN OHLv2) device that routes analog signals to the analog pins on the DVI connector and has an optional low pass filter (LPF). It is designed for 15KHz (240p & 480i) retro gaming signals and will allow more flexibility to your setup, particularly if you need DVI for a capture card.
Insurrection Industries has made the SCART2DVI version of the SCART Cleaner available for purchase here. File:SCART2DVIv1.1.zip.
Introduction
This device is powered by USB and passes through audio and has toggle switches for both the LPF and sync stripper. It's recommended to start with both switches off and toggle on the features as needed. In most cases you'd need the sync stripper on. If you're not sure if your console already has a LPF (such as something modded with a THS7314) then try toggling to see if it removes noise.
Full Bill Of Materials
Here's some component links, to try and make your ordering easier! As an FYI, all small components are SMD 0603.
Here's an all-in-one BOM (without the SCART connector) based on the below links (personally untested) that might make ordering easier: [1]
- Capacitor 0.1uF (100nF): [2]
- Capacitor 100uF: [3]
- Inductor: [4]
- Audio Jack: [5]
- MicroUSB Port: [6]
- Resistor 75ohm: [7]
- Resistor 100ohm: [8]
- Resistor 680k: [9]
- MicroSwitch: [10]
- THS7374: [11]
- LM1881: [12]
- SCART Connector, female: [13] [14]
- DVI Input Port: [15]
- Screws: [18]
Troubleshooting
If audio is too quiet for you, replace the components in R7 & R8 with 0 Ohm resistors ([https://www.digikey.com/product-detail/en/CRCW06030000Z0EAHP/541-0.0SBCT-ND/2222749/ link)
