TUSB542 Question and implementation

Other Parts Discussed in Thread: TUSB542, TUSB321AI, TPS2021

Hello Team,

My customer has found a discrepency in the datasheet and would like clarification.  Can you advise on below?

We’re in the middle of coding symbols and have noticed a discrepancy in the TUSB542 datasheet.

 

Page 8 shows:

cid:bd8a9809-b5d8-41ca-8b19-d878417fa810

 

Whereas in the table it shows:

cid:39967c06-e654-4047-a76a-6da911231711

 

Which is correct?

Also can you validate below is a good implementation - any other recommendations w/ resepect to app notes etc.

TUSB321AI – CC Control IC

TUSB542 – USB 3.1 Gen1 5G 2:1 Redriver/Mux

TPS2021 – VBUS power switch / current limit

 

Below is the customer implementation

 

Any guidance/app notes would be appreciated. We are not interested in supporting USB-PD. We would like to reuse the existing USB2.0 PHY.

 

Attached is a simplified block diagram of the implementation

 

 

Sincerely,

Dan Nitta Mackay TSR Ottawa Canada
