TUSB217A-Q1  
SLLSFK6 – SEPTEMBER 2021  
TUSB217A-Q1 USB 2.0 High-Speed Signal Conditioner With DCP and CDP Controllers  
1 Features  
3 Description  
•
AEC-Q100 qualified for automotive applications  
– Device temperature grade 2:  
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.  
-40°C to 105°C TA  
•
•
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-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.

•
•
•
•
Host or device agnostic  
Supports up to 5-m cable length  
The TUSB217A-Q1 improves signal quality without  
altering packet timing or adding propagation delay or  
latency.  
– Four selectable signal boost (edge boost along  
with DC boost) settings through the external  
pull-down resistor values  
– Three selectable RX equalization settings  
through the pull-up-or-down to compensate ISI  
jitter for high-loss applications  
Supports up to 10-m cable length with two  
TUSB217A-Q1 devices  
Scalable solution – devices can be daisy chained  
for high loss applications  
RWB is pin compatible with TUSB211/212/214/216  
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.
