USB2517 High Speed USB 2.0 Multi TT 7 Port Hub Customer Evaluation Board
The SMSC USB2517 MultiTRAK™ is a Low-Power Full-Featured High-Speed USB 2.0 compliant hub with seven down-stream ports. The EVB-USB2517 Evaluation Board demonstrates a standalone application for the hub with advanced power saving options and configurable port assignments. It is a demonstration and low-cost evaluation platform that robustly demonstrates the unique features of this device using a low-cost PCB implementation with individual port power control.
The EVB-USB2517 is designed for a low cost, power efficient implementation of a High-Speed USB Hub that supports internal default hub configurations as well as optionally supports an external EERPOM configuration. This evaluation platform supports a red LED indicator for the High-Speed hub state as well as standard USB Amber/Green LED indicators for operational state indication.
Applications: LCD monitors, TVs, Multi-function USB peripherals, PC mother boards, Set-top boxes, DVD players, DVR/PVR, Printers, Scanners, PC media drive bay, Portable hub boxes, Mobile PC docking, Embedded systems
