Hello

The distance between my GPU to Display port connector is moe than 8000 mil.

Could you please recommende a Re-driver ? I don't want to use AUX and HPD pin. They connect directly already to my GPU

What is the insertion loss of the 6000mil trace?

The placement of SN65DP141 as shown in your schematic is OK, the equalizer of SN65DP141 would compensate for the 6000mil trace loss, the equalizer would be set close to the loss of the 6000mil trace.

I noticed in your schematic that the output is being labeled 'DVI', what is your input and output?

Thanks

David

Hello David

My carrier board inculde SOM (Connect with B2B connector to my carrier board ) and display port connector.

SOM(COM100-B) -> Dispay Port Connector (On my carrier board)

The labeled 'DVI' is wrong.

The SN65DP141 is optimized for both trace and cable application at its input. The device pin EQ_MODE sets the EQ gain curve profile suitable for these two use cases. Please see section 8.4.3 and section 8.4.4 for the EQ configuration.

Thanks

Hello

Should I connect 100 ohm Termination Resistor between the Differential input ?

100ohm termination should already present inside the DP141, you only need to AC couple the inputs.

Thanks
