3 Description

The TUSB217A-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 TUSB217A-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

TUSB217A-Q1 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

TUSB217A-Q1.

The TUSB217A-Q1 improves signal quality without

altering packet timing or adding propagation delay or

latency.

The TUSB217A-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 TUSB217A-Q1 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 through a control pin.
