9.1 Application Information

The TUSB1042I is a linear redriver switch designed specifically to compensate for intersymbol interference (ISI) jitter caused by signal attenuation through a passive medium like PCB traces and cables. Because the TUSB1042I has one upstream facing USB 3.1 Gen1/Gen2 input, and two downstream facing USB 3.1 Gen1/Gen2 inputs, it can be optimized to correct ISI on all those three inputs through 16 different equalization choices. Placing the TUSB1042I between a USB3.1 Host and a USB3.1 Type-C receptacle can correct signal integrity issues resulting in a more robust system.
