EVB-USB5744

The EVB-USB5744 is a demonstration and evaluation platform that provides the necessary requirements and interface options for evaluating the USB5744 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-USB5744 into the user’s design. The EVB-USB5744 is compliant with the USB 3.1 Gen 1USB 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 1compliant. 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.
