Kit Overview

The Analog Devices has introduced the ADuM4160ADuM4160 and ADuM3160ADuM3160 USB isolators to address the difficult task of isolating the bus. The EVAL-ADuM4160EBZEVAL-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 ADuM4160ADuM4160 and ADuM3160ADuM3160 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

Connect to systems through standard USB Type A and Type B connectors.
Draw power from the USB host or from an external 5.0 V or 3.3 V power supply.
Support isolated power for the downstream interface through an ADuM5000ADuM5000 isoPower® dc-to-dc converter.
Support external downstream power from a 5 V or 3.3 V power supply.
Provide test points for all power and signal paths.
Support low and full speed communications.
Support enumeration control.
Support external ESD protection.
Support common-mode chokes in the xD+/xD− lines.
Support ferrite inductors in the VBUSx and GNDx lines.

Key Applications: USB peripheral isolation, Isolated USB hub, Medical applications

Kit Features

Key Features of the isolator include the following:

The ADuM4160ADuM4160 and ADuM3160ADuM3160 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.
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).
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.
