IIBERT 7 via DisplayPort 1.2 Card

Jump to solution

Hi,

 

We are trying to do eys scan of IBERT IP, via this DisplayPort 1.2 Card.

Hey @eunchong,

I don't see a problem with an eye scan with this card, but note that you won't get the on-wire signal, as you are passing the data through the adaptive receiver equalizer of the SN65DP159.

 

Best,

Herbert

Hi @hpoetzl,

 

 

Thanks your reply! We are glad to hear that we can do eye scan. BTW, are you using IBERT 7 series IP or DisplayPort IP? and can you use up-to 10 Gbps line late on Display Port?

Hey @eunchong,

 

Thanks your reply!

You're welcome!

Neither.

 

and can you use up-to 10 Gbps line late on Display Port?

The hardware I have currently available doesn't allow for 10 Gbps line rate.

 

Best,

Herbert

Hi @hpoetzl,

 

Thanks very quick replying! We are surprised that you don't use both IP but can do eye scan. How do you do eye scan? is it your own code?

I didn't say that I can do eye scans, although I can if I need to.

 

How do you do eye scan?

Eye scan with multi gigabit tranceivers is rather trivial. Simplified you have an offset (horizontally and vertically) to the sampling point and you just compare the result, do some statistics for each point and voila, eye scan diagram.

 

is it your own code?

Haven't written code for the Xilinx MGTs yet.

 

Hope this clarifies,

Herbert
