TUSB1002 Dual-Channel Linear Redrivers

Texas Instruments' TUSB1002 is the industry’s first dual-channel, USB 3.1 SuperSpeedPlus (SSP) redriver and signal conditioner. The device offers low power consumption on a 3.3 V supply with its ultra-low-power architecture. It supports the USB 3.1 low-power modes which further reduces idle power consumption.

The TUSB1002 implements a linear equalizer, supporting up to 15 dB of loss due to inter-symbol interference (ISI). When USB signals travel across a PCB or cable, signal integrity degrades due to loss and inter-symbol interference. The linear equalizer compensates for the channel loss, and thereby, extends the channel length and enables systems to pass USB compliance. The dual-lane implementation and small package size provides flexibility in the placement of the TUSB1002 in the USB 3.1 path.

The TUSB1002 is available in either a 24-pin, 3 mm x 3 mm WQFN or a 24-pin 4 mm x 4 mm VQFN package. It is also available in commercial grade (TUSB1002) or industrial grade (TUSB1002I).
