Hi!
We are making special kind of HDMI-to-USB Type-C adapter where we intended to use CCG3 together with Parade PS8743. Since there is a built-in aux-mux in that mux, is there any need for us to route AIUX/SBU via the CCG3? We can apply AUX pull-up/down separately. We planned base the FW on the CYPD3125 Notebook code since we will design is rather similar to the EVK base-board design (external DP input, USB-C is DP source). Anything to consider in this combination?
Cheers
Olof

Hello,
The purpose of the crossbar in CCG3 is to detect for plug connection orientation and route the SBU lines to the AUX of Display depending on the connection. If this functionality can be met using the external Mux and if the respective pull ups can be added then you may route the SBU signals directly skipping the CCG3.
