Xbox Open Source Video Project
XOSVP is an open-source printed circuit board by DiscoStarslayer, from the DiscoStarslayer/XOSVP repository on GitHub. It is a 2-layer board of 49.5 × 50 mm with 14 parts on 12 nets, routed with 210 tracks and 373 vias.
It is built around the PLT133/T10W and THS7316D. Its parts include 6 resistors and 3 capacitors.
XOSVP is an open-source alternative to the Microsoft HD AV Pack. The XOSVP strives to produce the absolute best analog video quality out of your original Xbox.
All designs are produced with KiCAD 5. This includes all schematic sources, designed footprints, and PCB layout.
Also within this repo is a 3D printable enclosure for the XOSVP. It is designed for friction fit so please ensure your 3D printer is calibrated properly before printing. All files were exported with Millimeter scale.
The enclosure was designed with Tinkercad, and you can view this design HERE.
I want high-quality analog video from the original Xbox to be available to everyone, which is why I open sourced this project. Everything within this repo is covered by CERN Open Hardware License v1.2.
If you have any suggested changes/improvements, please feel free to create an issue or a PR. They will be happily accepted!
The Following image contains all the parts in the BOM/XOSVP DIY Kit:

The parts are placed on the board in the following configuration

The 3D Printed enclosure is designed for a friction fit, so it is very important that the Y/Pb/Pr jack and VGA connector are completely flush to the PCB like in the following image:

To make the cable that connects the Xbox to the AVIP, you will need to splice the included AVIP connector with the included VGA cable.
Creating this cable is a rather involved process, and you want to get it right, so I created the following video tutorial to document the process I follow when making them.
The following pinouts are provided for extra detail and are intended to be used alongside the video tutorial.
This splice must follow the following pinout guide

Each of the colored AVIP pins must be connected so that they match the following pinout of the VGA cable. The only exception is the AVIP JMP 1 and AVIP JMP 2 pins. These need to be jumped together on the top + bottom of the AVIP connector.

The 13 most common of 14 parts.
It measures 49.5 × 50 mm and has 2 copper layers, 1.6 mm thick.
14 parts, built around the PLT133/T10W and THS7316D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the DiscoStarslayer/XOSVP repository on GitHub, at the commit this page was made from: the board is xosvp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask DiscoStarslayer before reusing the design.
