TUSB212-Q1: General Questions

Hi,

Can you help to clarify a couple of questions from my customer with regards to TUSB212-Q1?

<Q1>:

Could you please let me know how TUSB21x series operate?

As my understanding, the device attempts to detect its signal rising/falling edge of HS, then try to inject current to "boost" rising / falling edge.
It's appreciated if you have a document which describes operational basics.

<Q2>:

If my understanding above is right, the changing EQ setting change injected current.
Do you have injected current values for each EQ setting?

<Q3>:

Do you have the eye diagram with different EQ and DC setting for the condition below?

Upstream SQ Test
- Host
- Near End Mask
- Several different cables (like 1m, 2m...)


Thanks,
Ken
