Part Number: HD3SS460EVM-SRC
I am a bit new to the world of USB Type-C, but I am trying to prototype a Display Port GPU to USB-C (Displayport alternate mode) Monitor adapter. I am trying to use a MacBook or Desktop Computer as the Displayport and USB source and the LG Ultrafine 4k as the USB-C destination.
I purchased the HD3SS460EVM-SRC overlooking the fact it is passive and needs a cc controller so I have purchased the TPS65982, I am wondering how I go about linking the two? I have read online that the TPS65982 has booster pack. I am wondering if the pinouts are compatible or whether I need to use jumpers and if so which pins I need to link to have the TPS65982 negotiate a Displayport alt mode connection for the HD3SS460EVM-SRC.
Any help would be greatly appreciated..
Please send me an email to firstname.lastname@example.org so I can provide the schematics and the description on how to connect both boards.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Ferdinand Feltens:
I've used the HD3SS460EVM-SRC @ 4K, not with the LG monitor but using a DELL one and with multiple Type-C docking stations.
In reply to Diego Cortes:
my HD3SS460EVM-SRC module arrived today, unfortunatly the LG Ultrafine 4k is not showing any sign of connection, I suspect I too may need the TPS65982 Evaluation Module to "force" my GPU and the LG Ultrafine in an Displayport Alt mode connection, which they do not seem to establish themself.
Is this even a feasible plan? If so, could you provide me with necessary schematics and plans to connect the two boards?
Thank you very much, any help is greatly appreciated
Hello Ferdinand, That´s correct, you need a PD controller (The TPS65982 works well) in order to configure the Type-C port on the monitor and get a successful connection. Please send me an email to email@example.com to provide the schematics.
That´s correct, you need a PD controller (The TPS65982 works well) in order to configure the Type-C port on the monitor and get a successful connection. Please send me an email to firstname.lastname@example.org to provide the schematics. you also need the firmware for the TPS65982. Please create another E2E post to request the firmware and make sure to mention the TPS65982 in the title so the expert will help you shortly.
I also recommend using the TUSB1046EVM, which is a single board solution that combines the Type-C MUX and the PD controller. It also provides signal compensation that allows the usage of longer cables.
I now have HD3SS460EVM and TPS65982. I connected both CC1 and CC2 and GND of the boards and I do get a working USB Connection from the HD3SS460EVM micro USB input as well as LED A of TPS65982 is on, indicating Displayport alternate connection but unfortunatly there is no video signal. I tried mode 5, 8 and 9.
Also I did not manage yet to upload firmware via TPS65982 Customization/Utility tool. I only have a USB C to A cable, which should work according to the guide?
You must connect the CTL0, CTL1 and POL signals, we recommend to connect them as in the next paragraph. However, you must check that it is compatible with the firmware you have in the TPS65982. This is more related to the TPS65982, so I recommend to create a new e2e thread with the TPS65982 in the title so the right engineer will reply the queries regarding the TPS device and here the HD3SS460 related questions.
