Hello David,

Tha

nks a lot. I was able to open board in free allegro viewer. We are using Mentor graphics. That help me lot. But one think is a new question. Why You have on PCB display port differential pairs routed with 90 Ohm. While in datasheet in layout guide is recommended 100 Ohms? Could You please explain to me.

Thanks

Martin

I'm actually not sure why the EVM layout would say 90ohms. From the DP specification, high-speed traces are spec'ed at 100ohms +-10%.

But lower PCB impedance does tend to have some advantages, for example, they includ lower losses, have more tolerance to impedance variation, etc.,

Thanks
David
