INTRODUCTION
USB use has displaced older communications standards, such
as RS-232, as the default serial communications port in PC-based
systems. When compared to these other standards, USB has
many enhanced features, such as power for peripherals, automatic
driver installation, and higher data rates. However, when using
USB, it is difficult to provide isolation, which has limited its
acceptance in medical and industrial applications.
Analog Devices, Inc., has introduced the
ADuM3160
isolating the bus. The EVAL-ADuM4160EBZ USB isolator
evaluation board was constructed to allow an easy interface to
existing applications by standard cabling or discrete wiring.
The USB evaluation board comes populated with an
ADuM4160; however, because the ADuM4160 and ADuM3160
are electrically identical and pin compatible, any evaluation
done with this board and component applies directly to the
ADuM3160. If for some reason the user wants to substitute
theADuM3160 on the PCB, no other changes are required.
The design goals of this evaluation platform are to

FEATURES OF THE ADuM4160/ADUM3160
The ADuM4160 and ADum3160 provide support for full speed
and low speed data communications by interfacing directly with
the USB xD+ and xD− lines. The parts are designed to be
transparent to USB data traffic other than adding about as
much delay as a hub and cable. Features of the isolator include
the following:
The upstream side of the isolator includes Pin 1 through Pin 8,
is connected to the left side of the evaluation board, and
interfaces through a Type B connector. The downstream facing
side includes Pin 9 through Pin 16, is connected to the right
side of the evaluation board, and interfaces through a Type A
connector.
The evaluation board allows configuration of all of the features of
the ADuM4160/ADuM3160 chip and provides support for a
variety of possible power schemes. The board also allows
common-mode voltages; however, it is not recommended for
performing safety related testing, such as high voltage withstand
testing. Perform this type of testing on the component level or on a
production board.
Evaluation Board User Guide
Built-in voltage regulators allow the ADuM4160 and
ADuM3160 to draw power from either 5 V or 3.3 V
sources.
Application of the upstream pull-up resistor is under the
control of a downstream pin, PIN (Pin 12).
The operating speed of the isolator is set by pins on the
upstream and downstream sides of the part, SPU and SPD
(Pin 5 and Pin 13, respectively).
