EVB-USB5734 EVB-USB5734 USB3.1 Gen1 Controller Hub Evaluation Board

The EVB-USB5734 is a demonstration and evaluation platform that provides the necessary requirements and interface options for evaluating the USB5734 Smart Hub on a 4-layer RoHS-compliant Printed Circuit Board (PCB). This will allow the user to gain an understanding of the product and accelerate the integration of the EVB-USB5734 into the user’s design. The EVB-USB5734 is compliant with the USB 3.1 Gen1 USB Specification and supports Super-Speed (SS), High-Speed (HS), Full-Speed (FS), and Low-Speed (LS) USB signaling for complete coverage of all defined USB operation speeds. The evaluation platform supports four downstream ports that are USB 2.0 and USB 3.1 Gen 1 compliant. The EVB-USB5734 is also designed for flexible configuration solutions. It can be configured via default internal register settings, downloadable external firmware to an on-board SPI Flash, through SMBus, or through the on-board configuration switches. Five IO daughter cards are included in the EVB-USB5734 kit. Each IO daughter card initiates a predetermined User Configuration for the USB5734. All new functionality - FlexConnect, I/O Bridging, downstream speed and charging management, UART interface - can be demonstrated using these daughter cards.
