The TUSB1042I is a redriving switch supporting USB 3.1 data rates up to 10 Gbps. The TUSB1042I provides several levels of receive linear equalization to compensate for inter-symbol interference (ISI) due to cable and board trace loss. The device operates on a single 3.3 V supply and comes in the industrial temperature range.
