Part Number: TUSB501

Hi Sirs,

Sorry to bother you.

We are test fail on intel IEMT port5

The USB3.0 RX SI report as below (EQ=L DE=F OS:H is the best setting for us)

EQ:F/ DE: F/ OS: H

EQ:F/ DE: H/ OS: H

EQ:L/ DE: F/ OS: H

Looks waveform are OK but when we run IEMT tool will be fail.

So, could you share experience for us how to fix it?

Thanks!!

TUSB501 is a single channel redriver, are you use two of them? For the eye diagram you captured, is this from PCH or from the device?

Thanks
David
