7.1 Overview

The TUSB1002 is the industry’s first, dual lane USB 3.1 SuperSpeedPlus redriver. As signals traverse through a channel (like FR4 trace) the amplitude of the signal is attenuated. The attenuation varies depending on the frequency content of the signal. Depending the length of the channel this attenuation could be large enough resulting in signal integrity issues at a USB 3.1 receiver. By placing a TUSB1002 between USB3.1 host and device the attenuation effect of the channel can eliminated or minimized. The result is a USB3.1 compatible eye at the devices receiver. With up to 16 receiver equalization settings, the TUSB1002 can support many different channel loss combinations. The TUSB1002 offers low power consumption on a single 3.3 V supply with its ultra low power architecture. It supports the USB3.1 low power modes which further reduces idle power consumption. The TUSB1002 settings are configured through pins. In addition to equalization adjustment, the TUSB1002 provides knobs for adjusting DC gain and voltage output linearity range.
