Dual channel linear redriver has ultra-low-power architecture

Texas Instruments’ TUSB1002 is claimed to be the industry’s first dual-channel USB 3.1 SuperSpeedPlus (SSP) redriver and signal conditioner. The device offers low power consumption on a 3.3V supply with its ultra-low-power architecture. It supports the USB3.1 low power modes which further reduces idle power consumption. The device implements a linear equaliser, supporting up to 15dB of loss due to ISI. When USB signals travel across a PCB or cable, signal integrity degrades due to loss and inter-symbol interference. The linear equaliser 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 device in the USB3.1 path. The device is available in either a 24-pin 3mm × 3mm WQFN or a 24-pin 4mm × 4mm VQFN. It is also available in a commercial grade (TUSB1002) or industrial grade (TUSB1002I).
