8 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

8.1 Application Information

The TUSB1104 is a linear redriver designed specifically to compensate for intersymbol interference (ISI) jitter

causes by signal attenuation through a passive medium like PCB traces or cables. Placing the TUSB1104

between the USB connector and a USB 3.2 host, hub, and device can correct signal integrity issues resulting in

a more robust system.
