Can USB3.0 redriver IC be used for usb 2.0 port

YUTI TRIVEDI

Dear Tech Support Team,

Considering that the USB3.0 is backward compatible to USB2.0; can the USB3.0 redrivers mentioned as a part of TI website catalogue be used for the USB2.0 port.

Yuti,

The short answer is no.

USB 3.0 is backwards compatible to the end-user due to the physical characteristics of the connector. Electrically they are very different. The SuperSpeed signals are transmitted over new contacts added into the connector. The USB 2.0 D+ & D- data lines remain identical and are used to transmit the USB 2.0 signals.

For more information, I would recommend you review the SuperSpeed USB overview either on the TI home page or on the USB-IF Website.

Dear Sir,

Do you have a redriver built for USB2.0.

No we do not, nor am I aware of one available in the market.

Typically a USB 2.0 high speed hub is used to redrive the USB 2.0 data lines as the USB 2.0 spec limits the cable length to five meters before a hub is needed.
