I am using an FX3 and FGPA with a camera to send Images to a host over USB 3.0, so I am just using the SS signals on the USB 3.0 bus.  I don't see a reference design for this case.  What is the best USB Type-C PD device and I am pretty sure the I need a high speed mux for the SS signals.  Finally, what FW is available?  I am looking for the smallest size total design.

Thank you,

Mike Roberts

Hi,

Yes, a MUX is needed. MUX will not afftect the USB signal. You can refer to this KBA​.

Hi Mike,

You can take a look at our newest product ACG1F. It's dedicated for transferring Type-A to Type-C products. BCR is also applicable, but you'll have to design external MOSFETS gate.

I was thinking that the BCR would be good, but I don't know a recommended high speed mux and how to control it.  What do you recommend?  Is there a reference design just for this?  No Display Port, No Thunderbolt.  Just need to mux the USB 3.0 SS signals. I am space limited, so I am looking for the smallest solution.

Do I need a mux?  Can I just tie TX1+ to TX2+, TX1- to TX2-, RX1+ to RX2+ and RX1- to RX2-.  Only the FX3 is on these signal.  Is there an issues with open stubs @ 5Ghz?
