TUSB2E221: USB2 trace impedance

Part Number: TUSB2E221

Hi Team,

The intel spec need USB2 trace impedance should be 80 ohms ± 10%, but the USB2 spec need impedance should be 90 ohms ± 15%,

So, the customer project match USB2 trace impedance should be 80 ohms ± 10%, they want to check if there any risk? 

Now, the customer can pass SI test.

Many thanks~
