Part Number: TUSB1046EVM

Hi guys.

I have TUSB1046EVM and TUSB564EVM. and i'd like to use as DP --> USB C --> DP signal converter.

so I connect both EVM Kit like below.

1. PC(DP out) --> DP Cable --> TUSB1046 and PC(USB) --> TUSB1046

2. TUSB1046EVM --> USB-C --> TUSB564EVM

3. TUSB564EVM --> DP Cable --> Monitor and TUSB1046EVM --> USB Mouse

Result

1. PC detect monitor, but dose not activated monitor. and can not change monitor resolution.

2. PC detect USB Mouse.

How can I activate monitor?

and can I get TUSB1046EVM and TUSB564EVM original project file?

additional info

I have FT4232 debugging tool and installed TPS6598X application program.

Hi Hyojin,

What is the actual resolution you are trying to support? TUSB1046 can support USB up to 10Gbps and DP up to 8.1Gbps.
Do you have a USB Type-C protocol analyzer that can decode both the USB Type-C PD and DP link training protocol? On the Type-C PD protocol, please make sure both sides entering into the DP Alt Mode.

Best,

Josh

Thank you for your comment..

I tryed another PC( DP1.4 Version), and I could see screen video.

and first tryed PC DP Version is 1.2.

so that cause maybe related to the DP Version.

Hi Hyojin,

It makes sense. Please the comparison table between DP 1.2 and DP 1.4 below for you reference. I guess I can close the ticket.

Best,

Josh
