8.1 Application Information

The purpose of the TUSB216I is to re-store the signal integrity of a USB High-speed channel up to the USB connector. The loss in signal quality stems from reduced channel bandwidth due to high loss PCB trace and other components that contribute a capacitive load. This can cause the channel to fail the USB near end eye mask. Proper use of the TUSB216I can help to pass this eye mask.

A secondary purpose is to use the CD pin of the TUSB216I to control other blocks on the customer platform, if so desired.
