3 Description

The TUSB211A is a third-generation USB 2.0 highspeed

signal conditioner designed to compensate

both AC loss (due to capacitive load) and DC loss

(due to resistive loss) in the transmission channel.

The TUSB211A leverages a patented design to

speed-up transition edges of USB 2.0 high-speed

signal with an edge booster and increases static

levels with a DC boost function.

In addition, the TUSB211A includes a pre-equalization

function to compensate the inter-symbol interference

(ISI) jitter in application with longer cable length. USB

low-speed and full-speed signal characteristics are

unaffected by the TUSB211A.

The TUSB211A improves signal quality without

altering packet timing or adding propagation delay or

latency.

The TUSB211A helps a system to pass the USB 2.0

high-speed near end eye compliance with a cable as

long as 5 meters.

The TUSB211A is compatible with USB On-The-Go

(OTG) and Battery Charging (BC) protocols.
