9.1 Application Information

The TUSB564 is a linear redriver designed specifically to compensation for intersymbol interference (ISI) jitter caused by signal attenuation through a passive medium like PCB traces and cables. Because the TUSB564 has four independent DisplayPort 1.4 inputs, one upstream facing USB 3.1 Gen 1 input, and two downstream facing USB 3.1 Gen 1 inputs, it can be optimized to correct ISI on all those seven inputs through 16 different equalization choices. Placing the TUSB564 between a USB3.1 Host/DisplayPort 1.4 GPU and a USB3.1 Type-C receptacle can correct signal integrity issues resulting in a more robust system.
