Hi team,

Could you help to check the question from customer below? I can't find the answer on datasheet. Some of them may be too hard for me to understand, so need your help.

1. What is the power consumption of this device in HS active state? there is value in HS idel only.

2. The I/O voltage requirement and meet the protocol of eUSB2.0 and USB2.0, right? 

3. The equalization gain range meets the protocol of eUSB2.0 and USB2.0, right?

4. The equalization gain setting method meets the protocol of eUSB2.0 and USB2.0, right?

5. The pre-emphasis feature meets the protocol of eUSB2.0 and USB2.0, right?

6. The power-on reset method meets the protocol of eUSB2.0 and USB2.0, right?

    Hi Zhu Lijia,

    1. The power consumption will change dynamically based on the activity on the USB bus.  So, the power consumption will increase from idle if there is more USB traffic.  The power consumption should always be lower than the worst-case scenario shown below.

    2, 3, 4, 5, 6.  The TUSB2E11 meets ALL USB 2.0 and eUSB specifications.  Our team actually helped write the eUSB v1.1 spec, so we meet or exceed all requirements in the spec.

    Regards,
