Hi Experts,

Our customer currently is using TUSB211 as the USB2.0 signal redriver in below block diagram showing. After their test, they found there is no obviously changes for the D+/D- eye diagram, even changed the different EQ level. Can you help to suggest what is the recommended location for TUSB211 in below customer's use case? What's the possible reason for TUSB211 no effects in such application?

Thanks.

Hi Jacky,

Could you please share the eye diagrams captured? What is the CD pin voltage during testing? Where are they measuring the USB2 eye diagram?

Hi Malik,

After customer's comparison test with TUSB212, we found that TUSB212 will have more margin which can meet their test, so they changed to TUSB212 finally. Thanks for the help again.
