Hi,

My customer is using the TPS2549-Q1 (and TUSB211-Q1) and has a question.

Please refer the following attached file.

TUSB211 TPS2549 eye pattern.xlsx

Something like the overshoot occurs when not implementing the TPS2549-Q1 (and TUSB211-Q1),

and it is improved when by implementing the TPS2549-Q1 (and TUSB211-Q1).

Does this improving effected by TPS2549-Q1?

(Though I don't recognize that the TPS2549-Q1 (and TUSB211-Q1) works such as this...)

Best Regards,

Kuramochi

Hi Kuramochi-san,

What does your system look like to require both TUSB211 and TPS2549?

Do you have any eye diagrams where you implement only the TUSB211 and NOT TPS2549 or vice versa?

What type of signal is used to generate this eye diagram? Note: "Low Speed and Full Speed signal characteristics are unaffected by the TUSB211. High Speed signals are compensated by the TUSB211. "

Hi Kuramochi-san,

I haven't heard back from you in a while. If you think you've resolved this issue on your own, I will go ahead and close this thread.

Thank you,
Jaime
