Analog Devices Inc. EVAL-ADuM4165 and EVAL-ADuM4166 Evaluation Boards enable quick and easy evaluation of the ADuM4165 and ADuM4166 USB 2.0 Isolators, allowing direct connection to USB hosts and peripherals without the need for additional components. The ADuM4165 and ADuM4166 employ iCoupler® technology to combine isolator channels, USB transceivers, power and timing circuits, control logic and internal terminations, pull-ups, and pull-downs into a single, 20-lead, wide-body, increased creepage SOIC_IC package.
The Analog Devices Inc. EVAL-ADuM4165 and EVAL-ADuM4166 Evaluation Boards include an upstream facing port (USB Type-B connector) and a downstream facing port (USB Type-A connector) corresponding to the upstream Side 1 and downstream Side 2 of the ADuM4165 and ADuM4166 Isolators. The Isolators are designed to be transparent to USB data traffic other than adding between one and two hubs plus cable delays.
A host or a hub downstream facing port can connect to the USB Type-B connector, and peripherals or hub upstream facing ports can connect to the USB Type-A connector. Low speed, full speed, or high-speed devices can be connected to the Evaluation Boards. The ADuM4165 and ADuM4166 Isolator will automatically detect the speed and adjust the internal pull-ups and termination.
