Chapter 1. Overview
1.1 EVB-USB4715 OVERVIEW
The EVB-USB4715 is a demonstration and evaluation platform that provides the nec-
essary requirements and interface options for evaluating the USB4715, a 4-Port HS
USB 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 USB4715 into the user’s design. The USB4715 is compliant with USB 2.0
High-Speed (HS), Full-Speed (FS), and Low-Speed (LS) USB signaling. The evaluation
platform supports four downstream ports; two USB 2.0 ports with Type-C™ connectors
and two standard Type-A USB 2.0 ports. The EVB-USB4715 platform also supports
battery charging on all four ports (maximum of 10A* at any one time). The
EVB-USB4715 is configured for operation through internal default settings and sup-
ports custom configurations through SMBus or through the external 16-Mbit
SPI Flash
device. The EVB-USB4715 supports FlexConnect role reversal for any of the four
downstream ports with the upstream port. The EVB-USB4715 demonstrates driver
compatibility with Microsoft

10, Windows 8.x, Windows 7, Windows XP,
Mac OS

X 10.4+, and Linux
®
hub drivers.
