8 Re-drivers in other applications

Wherever there is an external USB2.0 port, cables of unknown lengths can be plugged into the USB2.0 port, which can cause the risk of failing USB2.0 compliance. One such application is in lightning to USB-C applications.

Lightning to USB Type-C USB2 Redriver Application shows how a TI-redriver can be used in between the Lightning to Type-C connector to handle cables of unknown length between them.

The USB re-driver is in an adapter, meant to adapt Lightning to USB-C, allowing Lightning based accessories to interface with the new Phone/ipad USB-C ports.
