TDP2044: USBSS(10Gbps) interface over this redriver

H Jayaraj
Intellectual 590 points
Part Number: TDP2044
Other Parts Discussed in Thread: TUSB1044, TMUXHS4446, TMUXHS4612

Tool/software:

We have both DP and USB SS muxed inside SoC. I see the datasheet says this is a DP2.1 redriver. Will this re-driver work if there is a USB SS signal @10Gbps through this IC?.

    Hi,

    TDP2044 is uni-directional, so you shouldn't drive USB SS signals through it. What DisplayPort data rate are you planning to use in your system? 

    If you can accept 10Gbps DisplayPort signals, consider the TUSB1044.

    Best,

    Hi,

    TUSB1044 looks good. But, this does not provide flip option. Does TMUXHS4446 DP pins are bidirectional. Can I give USBSS signal to DP pins since it's pin are mentioned as I/O?

    Do you have a similar device to TMUXHS4446 which support UHBR20?

    I believe TUSB1044 does support lane routing for flip and normal orientations. 

    Look at TMUXHS4612. This MUX will support UHBR20, but check that it fits your application.

    For more in-depth support I recommend submitting another E2E with the relevant part name. I can help with questions for TDP2044 but other parts are covered by other teams at TI.

    Best,
