7.1 Application Information

The TUSB1002A is a linear redriver designed specifically to compensation for ISI jitter caused by attenuation

through a passive medium like traces and cables. Because the TUSB1002A has two independent channels, it

can be optimized to correct ISI in both the upstream and downstream direction through 16 different equalization

choices. Placing the TUSB1002A between a USB3.2 Host/device controller and a USB3.2 receptacle can correct

signal integrity issues resulting in a more robust system.
