TUSB217A USB 2.0 High-Speed Signal Conditioner With DCP and CDP Controllers

1 Features

3 Description

•

Wide supply voltage range: 2.3 - 6.5 V

Ultra-low USB disconnect and shutdown power

consumption

Provides USB 2.0 high-speed signal conditioning

Compatible with USB 2.0, OTG 2.0 and BC 1.2

Support for low-speed, full-speed, high-speed

signaling

Integrated BC 1.2 Charging Downstream

Port (CDP) and Dedicated Charging Port

(DCP) controllers that dynamically changes per

DCP/CDP pin

The TUSB217A 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 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 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.

•

Host/Device agnostic

Supports up to 5-m cable length

– Four selectable signal boost (edge boost along

with DC boost) settings via external pull-down

resistor values

– Three selectable RX equalization settings via

pull-up-or-down to compensate ISI jitter for

high-loss applications

Supports up to 10-m cable length with two

TUSB217A devices

Scalable solution - devices can be daisy chained

for high loss applications

The TUSB217A improves signal quality without

altering packet timing or adding propagation delay or

latency.

The TUSB217A 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 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.

RWB is pin compatible with TUSB211/212/214/216
