The three reference designs for Display Port Cable Solutions show the USB 2.0 signals (D+/-) terminating in the Cypress CCGx or Billboard controller.

Can those USB 2.0 signals be brought out along side the Display Port Signals?

CCG2 Ref: https://www.cypress.com/documentation/reference-designs/ez-pd-ccg2-usb-type-c-displayport-cable-solu...

CCG3 Ref: https://www.cypress.com/documentation/reference-designs/ez-pd-ccg3-usb-type-c-displayport-cable-solu...

It appears, using the Hub Controller, HX3PD, both the Display port signals and the USB 2.0 signals can pass though.

Is that a special feature only available with he hub controllers and not the CCGx?

Hi Greg,

HX3PD also follow Type-C Power Delivery Spec and DisplayPort Alternate mode over Type-C SPEC. The DisplayPort signals never go through USB2.0 DP and DM signals. The USB2.0 HUB inside of HX3PD is for USB2.0 routing, you can see, there are 7 down-streaming ports on HX3PD.

Best Regards,

Lisa
