TUSB501 / USB3.0 compliance test

Other Parts Discussed in Thread: TUSB501

Hi Team,

I heard my customer's board failed "Rj-Tx random jitter" of the USB3.0 compliance test.
The measured value is 4.032ps although high limit of the test is 3.290ps.

The test condition is the following.
*certification equipment -> USB3.0 cable(1.8m) -> TUSB501 -> measurement equipment
*TUSB501: EQ=Floating(6dB), OS=Low(930mVpp), DE=Floating(-3.5dB)

Is the configuration of TUSB501 reasonable?

Best Regards,
