SN65DP141: SN65DP141RLJT schematic checklist and reference design

Part Number: SN65DP141

Hi,

I am currently designing schematic for display port for which i have selected SN65DP141RLJT. Is it possible i can get reference design schematic and board file of evaluation board? I could see some application circuit available in datasheet but while going to the forum link i am little confused about the AC coupling capacitors. While datasheet recommends to add AC coupling capacitor whereas forum suggests adding AC coupling capacitor will not meet DP specification and suggesting to replace capacitors with 0ohm resistor.

Can anyone please guide me on this?

The DP141 EVM is being designed with an input connector and an output connector. When connecting the EVM to a DP source, the source should already has AC coupling capacitors populated on its TX so there is no need for capacitors on the receiver input of the DP141 EVM. The only capacitors requirement is on the EVM output.

Would you please accept my friendship request so I can send you the EVM board file?

Thanks

David
