Hi ,

Could you please confirm if we can replace TUSB211 with TUSB216

Also, Can you please clarify if the shorting of USB DP/DM signals between Host and Connector, under the TUSB211/TUSB216 IC is compulsory/ optional .

Yes, the TUSB211 can be replaced by the TUSB216I: https://www.ti.com/lit/ug/slla558/slla558.pdf

The signals must be shorted under the device for good signal quality.

Hi,

Thank you for the clarification. The doc shared was greatly helpful.

Could you please also confirm if TUSB211/TUSB216 supports polarity inversion?

Hello Mounika,

No, the DP / DM lines must be routed to match the pinout of the device. Polarity inversion is not supported.

Hi,

When we informed the same to the vendor who provided reference schematic, he shared the below link indicating that swapping is allowed.

Could you please help us understand which is correct.

Hi Mounika,

We do not recommend swapping DP and DM lines for the later redrivers due to additional features.
