Hello,
My customer have some questions about DS100BR111.
[Q1]
Is the following connection (Figure 1) possible in SATA II (3G) application ?
(I read "DS100BR111 as a SATA Repeater", so I think it is OK.)

[Q2]
The following figures (Figure 2, Figure 3) are input EYE diagram of DS100BR111.
Are these input levels appropriate?
I think those are appropriate because there are differential signal level more than 190mVpp.

[Q3]
The following figures (Figure 4) are input EYE diagram of CPU.
That seems to be distorted.
Does anything know this cause ? Impedance mismatch ? overkill ?
Do you think it is improved by Equalizer and Emphasis ?
