Hi team,

4 Port SATA3.0

Originally used DS125MB203SQ, now does not need the function of Switch

The SATA signal from the source to the Redriver to the Connector may most often be 20"

Our customer is seeing DS125BR401A on Ti’s website, and they would like to ask if the A-Channel and B-Channel written in him only mean that the values that can be adjusted are different?

Are other parts such as the signal length the same as the original DS125MB203SQ?

Thanks

Hi Paul,

1). A-side is more link a linear equalizer and it has more linearity range versus B-side with its limited linearity range.

2). Parts similar to DS125MB203 functionality are: DS125BR800 and DS125BR401.
