We have developed a board for converting Display Port standard to VGA standard using PTN3392. We are not able to get Display Port signals and so there is no output in VGA standard.


When I probe on Display Port Main Lane signals all are just high at 0.8V logic and AUXP & AUXN signals are high at 1.2V logic.


And also our board is not receiving power from Display Port cable. 


Hereby attaching our schematics for your reference, Can you please help us to overcome the issue?


Thank you.
