3 Description

The TUSB1002A is the industry’s first dual-channel

USB 3.2 x1 SuperSpeedPlus (SSP) redriver and

signal conditioner. The device offers low power

consumption on a 3.3V supply with its ultra-low-

power architecture. The device supports the USB3.2

low power modes which further reduces idle power

consumption.

The TUSB1002A implements a linear equalizer,

supporting up to 16dB 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 TUSB1002A in the USB3.2 path.

The TUSB1002A is available in either a 24-pin 4mm ×

4mm VQFN. It is also available in a commercial grade

(TUSB1002A) or industrial grade (TUSB1002AI).
