Chapter 1. Overview
1.1
INTRODUCTION
The EVB-USB7206 is a demonstration and evaluation platform that provides the nec
-
essary requirements and interface options for evaluating the USB7206, a 6-port
High-Speed (HS) USB smart hub on a 4-layer RoHS-compliant Printed Circuit Board
(PCB). This allows the user to gain an understanding of the product and accelerate the
integration of the USB7206 into the user’s design.
The EVB-USB7206 is compliant with the USB 2.0 HS, Full-Speed (FS), and Low-Speed
(LS) USB signaling. The EVB-USB7206 is also compliant with USB 3.2 Gen2 on the
upstream port and on downstream ports 1 to 5.
The evaluation platform supports six downstream ports: five Gen2 ports, and one
USB2.0 port with Type-A connectors. The EVB-USB7206 platform also supports bat
-
tery charging on all six downstream ports (maximum of 10A;
see
) at any one
time. The EVB-USB7206 supports FlexConnect role reversal for any of the six down
-
stream ports with the upstream port.
The EVB-USB7206 has four configurations for operation through internal default set
-
tings and supports custom configurations either via I
2
C or through the external 16-Mbit
SPI Flash device.
The EVB-USB7206 demonstrates driver compatibility with Microsoft
®
Windows
®
10,
Windows 8.x, Windows 7, Windows XP, Mac OS
®
X 10.4+, and Linux
®
hub drivers.
