Other Parts Discussed in Thread: HD3SS6126, TUSB8041, TUSB8020B

Dear Sir/Madam/Miss,

Do HD3SS6126 chip support for 8:1 multiplexer (USB 3.0)? Since its only designed for 2:1/1:2, I'm wondering can I cascade it into 8:1.

Is that will be a problem in signal integrity if I cascaded it into 8:1 using this chips ? I had attached a picture file for better view.

Hello,

I think that it can be done, please give me more time to confirm whether is possible or not.

Dear bro,

Hereby I had attached a picture of another new idea for 8:1 mux using HD3SS6126

Based on the new idea, can I connect all the HSA +/- pin, SSA0 +/- pin and SSA1 +/- pin together respectively ?

Is that any user had implemented it ?

How about the signal integrity ?

I had drawn and uploaded it "BlockDiagram3.png".

Kindly waiting for your reply bro.

Thanks

Regards,

Shagilan Bala

Dear Sir/Madam/Sis/Miss,

Hereby, I had attach a new picture of 4:1 multiplexer for USB 3.0.

Is this diagram ok for me to develop this project ?

How about its transmission delay & signal integrity?

Hello,

Sorry for the delay.

I recommend you to use a USB hub instead. With your current implementation only one USB device will be available and every time you switch to another device it will have to be re-enumerated.

All the devices will be available at any time if you use a USB hub.

I recommend you to look at the TUSB8041, TUSB8020B.
