Other Parts Discussed in Thread: TUSB211, TUSB216
Dear TI experts,
My customer changed USB redriver from TUSB211 to TUSB216 due to apple carplay disconnect issue about 1 year ago.
This time they have a problem with Android auto.
old android phone seems okay, but new phone (Samsung Galaxy S21 and newer - S22, S23 series) have disconnect issue while using.
They checked eye diagram, and they saw that newer phones have higher DC voltage level. (about 500mV or more)
old android phones and iphones have lower DC voltage level. (about 400~450mV)
Did you have any silmilar issues to other customers? and how can we fix it?
I have a measured eye diagram but it is confidential. I can send it to you if you want. (please send me the friendship request.)
Please check this issue. Thanks.
Best regards,
Chase
