Dual-channel linear redriver offers ultra-low-power architecture

The Texas Instruments TUSB1002A is claimed to be the industry’s first dual-channel USB 3.2 x1 SuperSpeedPlus (SSP) redriver and signal conditioner. The device provides low power consumption on a 3.3V supply with its ultra-low-power architecture. It maintains the USB3.2 low power modes which further reduces idle power consumption. The device uses a linear equalizer, supporting up to 16dB of loss due to ISI. When USB signals move across a PCB or cable, signal integrity deteriorates due to loss and inter-symbol interference. The linear equalizer offsets for the channel loss, and thereby, increases the channel length and allows systems to pass USB compliance. The dual lane implementation and small package size gives flexibility in the placement of the device in the USB3.2 path. The device is offered in either a 24-pin 4mm x 4mm VQFN. It is also available in a commercial grade (TUSB1002A) or industrial grade (TUSB1002AI).
