Part Number: TUSB1002

hi,

I have some question in using TUSB1002.

The USB3.0 interface used now has USB3.0 switch and Hub on the circuit.

Does this affect the USB3.0 signal? Does it affect the USB3.0 certification test?

In addition, if you add USB1002 to ports near device and Host,

Is it possible to solve the effect of USB switch and Hub?

To meet the USB3.0 certification test.

thanks.

The purpose of TUSB1002 is to recover a compliant signal that has become lossy over a given channel, and boosts the output of that recovered signal, allowing a longer distance for that signal to travel. I would suggest to take a look at the following blog and reference white paper to get a better understanding of USB signal conditioning.
