DisplayPort Rx IP - fast connect

I am using the DisplayPort IP in an application which is a test environment where we will connect up a DisplayPort TX chip and want to quickly verify that it passes video correctly.   The roadblock currently is that the initial synchronization sequence takes on the order of 5-seconds which for us is an eternity.   With the path losses, etc being the same between each chip we test is there a way to have the connection assume a set of correction values and go with it?

Thanks.

Tim

Hi @tim_severance,

 

You should be able to skip the EDID read as you know the sink.

 

Not sure if that answers what you are asking...

Florent,
Do you know if it is possible to bypass training as well? Does this need to be co trolled from the DP source?
Thanks

Hi @tim_severance,

 

Yes it would be in the DP source.

 

I don't think you can bypass the training.

Re: DisplayPort Rx IP - fast connect

Hi @tim_severance

 

Please refer the followings. At least, it's important for DisplayPort.

 

- Must do link training.

- If the design is for Display Port not eDP, I suggest to implement EDID. It may be confuse DP source, if no EDID.

 

Thank you.

Best regards,
