Hi everyone,
after recently buying a Framework 13 I wanted to design my own Expansion Card for the Laptops. I have chosen to create a HDMI Capture Card. The project is still in it’s infancy, but I would like to get some feedback on the design.
Here is a link to the Github repo: GitHub - TheUnproductive/FrameworkHDMICaptureCard
The design is idea came after seeing this repo: GitHub - YuzukiHD/YuzukiLOHCC-PRO: Low cost USB3.2Gen1 HDMI-USB Video Acquisition With Loop Out (Loop Out HDMI Capture Card) base on MS2130 & MS9332
My design only uses the MS2130 and EA3059. The first chip is a HDMI to USB3.0 converter IC, the latter is used for supplying the MS2130 with the necessary voltages.
The initial design should be finished, but I am not very sure, if it will actually function the way I want. This is my first time working with any differential paired traces and I am not sure, if my idea, that it wouldn’t be necessary to trace them as differential pairs, was correct. (My reasoning behind this decision was basically, that the board is to small, that a millimeter of difference shouldn’t matter)
I hope you enjoy the idea as much as I do.
Happy New Year
