3 Description

The TUSB211A-Q1 is a third-generation USB™

2.0 high-speed 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-Q1 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-Q1 includes a preequalization

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-Q1.

The TUSB211A-Q1 improves signal quality without

altering packet timing or adding propagation delay or

latency.

The TUSB211A-Q1 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-Q1 is compatible with USB On-The-

Go (OTG) and Battery Charging (BC) protocols.
