The ISOLATED-USB-EK from Silicon Laboratories is an evaluation board aimed to accelerate the development of systems that need to be isolated among subsystems. This board is considered an expansion board, as it allows the user to expand the capabilities of the host.

This board is designed to reject common-mode transients, prevent ground loops, and provide galvanic isolation to support USB signals and other digital communication between subsystems in a system of systems environment. This board is built to be small, compact, and low-power, allowing the end user to customize the board to their own needs.

The main purpose of the ISOLATED-USB-EK is to provide effective isolation up to 2000V RMS and to reject common-mode transients. The board works by separating the signal ground and logic ground. As a result, the different grounds never directly touch or interact with one another. The board also supports system architecture for bi-directional data communication and power supply isolation.

This board can be used in different fields such as automotive, industrial, medical, communications, and more. The board is also featured to be used for true galvanic isolation, to reduce EMI, and to reject common-mode transients.

Working principle is also an important factor when considering the ISOLATED-USB-EK. The board takes the input of two signals, one that is already isolated and one that is not. Both these signals are then routed through a transformer, thereby connecting the two grounds. The board also routes the signals through two optocouplers, which convert the digital signals to analog, and then back to digital before sending it to the host.

The main benefit of using the ISOLATED-USB-EK evaluation board is that it allows users to create a low-power, isolated system. This board is also constructed to be small and compact, allowing users to customize the board according to their specific needs. The board is also constructed to reject common-mode transients and to prevent ground loops.

In conclusion, the ISOLATED-USB-EK evaluation board is a great tool to accelerate the development of systems that need to be isolated among subsystems. This board is featured for true galvanic isolation, to reduce EMI, and to reject common-mode transients. The board can be used in various fields such as automotive, industrial, medical, communications, and more, and it allows the end user to customize the board according to their own needs.
