Problem statement:
As most of you already know, the Xbox  DDC IC (aka booster) is not available for sale by the electronics distributors. When you get a 'no video' condition, the hope is that it's just the redriver, or the HDD. But when those have been replaced, and the circuit has been checked over, the next item is likely the DDC IC.
The current approach is to find a donor system to grab parts from. Purchasing the IC from third parties (like eBay) is costly.
There are diagrams floating around this group, and repair forums stating that you can "bypass" the DDC IC, but when you do so, you put the 3.3V level logic at risk of damage from the 5V HDMI port side. I do not recommend "bypassing" the DDC IC. You can cause irreversible damage to the SoC side.

Solution space:
So…how do we go about replacing the unavailable DDC IC for the One X, Series S and Series X consoles?
I present to you a low cost prototype of a discrete DDC IC alternative that I made. See pictures.
While this specific prototype design is focused for the Xbox One X, this is the same circuit used in the Series S and Series X consoles. It’s the same idea for both - just with a different board outline.

  1. Provides 5V @ 240 mA overcurrent protection on the port side in the event of a 5V short to GND.
  2. Provided an electrically isolated path of the low speed IO (LSIO) between the console and TV side when the console is shut off. This applies to the 5V, DDC SCL/SDA, and HPD signals.
  3. Provides electrical level translation from the 3.3V SoC side to the 5V HDMI port side (applies to DDC SCL/SDA, and HPD signals).
The parts are made by discrete devices that are commercially available from Mouser/DigiKey.
  1. Remove the defective DDC IC from the Xbox One X or Series X board.
  2. Place assembled PCB in the DDC area.
  3. Run jumpers to corresponding pads (the next revision of the PCB will have "half moon" solder pads instead of requiring you to run jumper wires)
