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
