Frequently Asked Questions
How many downstream USB ports does USB2517I-JZX support and what is its maximum data transfer rate?
The USB2517I-JZX supports up to 7 downstream USB 2.0 ports and achieves a maximum data transfer rate of 60 MBps (480 Mbps High Speed). This makes it suitable for connecting multiple USB peripherals such as storage drives, cameras, and communication modules to a single USB 2.0 host controller in embedded or industrial systems.
What configuration interfaces does USB2517I-JZX support and how are they used in system designs?
The USB2517I-JZX supports I2C, SPI, SMBus, and UART configuration interfaces, allowing a host microcontroller to customize hub parameters such as Vendor ID, Product ID, power allocation per port, and port enable/disable at startup. This programmability enables OEMs to tailor the hub's USB descriptor and power behavior without hardware changes, reducing time-to-market for custom embedded platforms.
At what supply voltage does USB2517I-JZX operate and what does 3.3 V operation enable in system design?
The USB2517I-JZX operates at 3.3 V, which is the standard logic supply voltage in modern embedded systems. This allows direct connection to 3.3 V microcontroller I/O without level shifters, simplifies power supply design by eliminating a separate 5 V logic rail, and reduces overall system power consumption in battery-powered or fanless embedded applications.
For a compact industrial embedded computer design, how does the QFN-64 package of USB2517I-JZX compare to larger package alternatives?
The QFN-64 package has a body size of approximately 9 mm x 9 mm with exposed thermal pad, offering a significantly smaller footprint than equivalent LQFP-64 or TQFP packages. The QFN's bottom thermal pad also improves heat dissipation, keeping junction temperature lower during peak USB traffic and improving long-term reliability in compact industrial PCs operating continuously at elevated ambient temperatures.
