描述
The ISL54220IRUEVAL1Z evaluation board is designed to provide a quick and easy method for evaluating the ISL54220 USB switch IC.
The ISL54220 is a single supply dual 2:1 multiplexer that can operate from a single 2.7V to 5.5V supply. It contains two single pole/double throw (SPDT) switches configured as a DPDT. The part was designed for switching or routing of USB high-speed signals and/or USB full-speed signals in portable battery-powered products.
The ISL54220µ TQFN IC is soldered onto the evaluation board. It is located in the center of the board and is designated as U1. The evaluation board contains USB connectors to allow the user to easily interface with the IC to evaluate its functions, features, and performance. For example, with the board properly powered and configured, you can control the logic pins, SE and OE, to switch between the two high-speed USB devices while connected to a single USB host (computer).
特性
- Standard USB connectors
- Standard banana jacks for power, ground, VBUS, and logic connections
- Jumpers to allow a device to be powered through the host controller
- Convenient test points and connections for test equipment
