Part Number: SN75DP130

I want to design using SN75DP130 in sink side.

[DP Connector (Source)] ----> [SN75DP130 Re-driver] --------> [ FPGA]

I has some questions

1. Datasheet has only source side guide. Do you have some reference schematic of sink side?

2. FPGA need AC cap in AUXSNK line like below. Can I put the AC cap in AUXSNK line?

[SN75DP130 Re-driver AUXSNK] ------> [AC CAP] --------> [ FPGA]

3.Refer to below image.

When I using as Sink side re-driver, AUX_SRCP/N, SCL_DDC and CAD_SRC is must be unconnected like below guide?

Hello SS

Unfortunately, we don't have any reference schematic, but if you follow the guide, you can build a correct schematic for this application.
As the guide says, AUX interface is only necessary when monitoring the D3 power state transitions of the sink. For more information, please take a look at the guide.
