Displayport is AC coupled at the source, so additional ac coupling caps arent needed at the converter. In fact, one of the key uses of this chip is to convert displayports ac coupled serdes into a dc coupled tdms signal. Secondly, strictly speaking this is to enable a dual-mode displayport connector to output to dvi, as true displayport signalling is actually packet based, and can run on anywhere from 1 to 4 lanes in differing applications.
Thanks for the info! I'm to hung up on the electrical side of those things (level shifting etc.) to deep dive into the higher protocol layers 😅 So, thanks again for providing that info!

As usb- c displayport alt mode doesn't support dual mode, usb-c to dvi adapters actually have protocol conversion built in.

@@varno Again, thanks for the info! USB C isn't even on my radar as a display interface 😅 But of course it's one of its functions.
