3 Description

The TUSB216I 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 TUSB216I 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 TUSB216I includes a pre-equalization

function to improve the receiver sensitivity and

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 TUSB216I.

The TUSB216I improves signal quality without altering

packet timing or adding propagation delay or latency.

The TUSB216I helps a system to pass the USB 2.0

high-speed near end eye compliance with a cable as

long as 5 meters.

The TUSB216I is compatible with the USB On-The-

Go (OTG) and battery charging (BC 1.2) protocols.

The Integrated BC 1.2 battery charging controller can

be enabled via a control pin.
