Vayne,

I am having trouble understanding your question? Your schematic seems to already have EQ configurations in your schematic through UEQ0, UEQ1, DEQ0, DEQ1, CFG0, CFG1.

Hi Sir,

The EQ is OK?

Vayne,

The EQ settings should be set based on the expected loss in you desired application. For cables you will need to measure the loss profile of your cable and match closely to the EQ numbers presented in Table 7 at the desired frequencies.

In addition it seems that this cable is designed for one direction as it only accounts for on direction when going from DP to Type-C, is this correct?
