TUSB1046 Re-driver EVM

Other Parts Discussed in Thread: TUSB211, TUSB1046-DCI

Hello,

I'd like to build some intelligence around the TUSB1046 and use the USB 2.0 interface (part of the USB C standard signals) to communicate with a USB host device.  Does the EVM enable this exploration? 

Similar to the TUSB1046 DisplayPort EVM, is there TI design available for HDMI? 

Thanks.

    Hello Manny,

    You only have to directly connect the DP & DM signals from the Host to the Type-C connector, the most common practice is short both DP & DM pins on the connector side, also if needed you can include a USB2 re-driver (TUSB211). Unfortunately, we do not have an HDMI solution for Type-C, in fact, this spec is still under development but most video sources supports DP++ or DP signaling, especially GPUs.

    Regards,
    Diego.

    Hello Diego,

    Can you explain further the reason why TUSB1046-DCI can't support HDMI? The bandwidth is less than DP and the signals can be AC coupled correct?

    Best Regards,

    Casey

    Hello Casey,

    By the time I answered this post we didn't have any test or specification to confirm whether the TUSB1046-DCI supports HDMI alternate mode. Now we can conclude that the device supports such mode, you only have to include the pull-up terminations for the HDMI source before the AC capacitors in the DP input of the TUSB1046-DCI.

    Regards,
    Diego.
