Could some one please explain to me why the inputs are swapped with respect to standard HDMI connectors.
HDMI connector starts at pin 1 as D2+ and goes across from there.
But the TMDS181 (if you place them next to each other on a PCB) starts with CLK-
This seems crazy to me. Why not line them up??? What am I missing?
As for the Swap function, it's less than helpful. As the polarity will only swap in retimer mode for higher rates.
So even if I set the SWAP/POL = H, the product will only work at 2.0 data rates.
I must be missing something, it can't really be this broken. Oddly enough the DP159 does not have this problem
I tried to attached a picture, but that does not seem to work, so I will try and outline the issue here in text.
HDMI standard connector mounted on the top of the PCB with connector end up and leads down.
1 2 3 4 5 6 ... etc
D2+ GND D2- D1+ GND D1- ....
Wires connecting them
TMDS181 rotated 90deg so pin one is top right.
12 11 10 9 8 7 .... etc
CLK- CLK+ 3.3V D0- D0+ GND
