Part Number: TPD8S009

HI,

I'm using the TPD8S009DSMR and TPD4E1DRLR ESD protection for DisplayPort extender board.

I'am routed this board using DP layout constraints, but the board (DP) doesn't work !!

I suspect the ESD protectionsdiodes ! have you any idea for the origin of this issue !

Please find attashed my design.

Best Regards,

    Hi,

    After examining your schematic, I see no issues with the connections pertaining to the ESD protection devices. Can you provide any additional information as to the issue? Have you attempted the same connection without the ESD protection to verify the root cause?

    Very Respectfully,
