TPS65983: TPS6598x role define and wake up question

Part Number: TPS65983

here are 2 questions about the TPS6598x

1) USB3 Dual Role function:

Coffee Lake USB3 Dual Role support Requirement:

customer don’t have EC on our M/B, does TPS6598x Fast Role Swap & Mode Configuration meet this requirement?

2)  Does TPS6598x support USB wake up function through USB type C?   

  • Hi Peter,

    We are looking into your query and will respond back as soon as we can.

    Thanks,

  • Hi Peter,

    Would this be for the Thunderbolt ports? This would be handled by the Thunderbolt controller. I believe the Coffee Lake RVP supports Thunderolt through the TR AIC, please refer to the 571483 Intel Document on page 7. The sleep and wake modes are connected to AIC through a GPIO header. The AIC could be implemented on the motherboard getting the PCIe from the PCH and graphics from the SoC.

    As far as not having an EC there should be an option to connect the PD controller to the PCH directly but this was an option on the previous chipsets. The new RVP board does have an EC defined in the design so this may not be allowed.

    I recommend you have the customer confirm with Intel before finalizing the architecture.
