USB2517I-JZX

Controllers Overview

The USB2517I-JZX is a USB 2.0 Hi-Speed 7-Port Hub Controller IC designed for embedded solutions. It features MultiTRAK technology with one transaction translator per port and supports Low-Speed, Full-Speed, and Hi-Speed downstream devices. The device operates on a 3V to 3.6V supply with a typical current of 130mA. It utilizes a 64-pin QFN package (9x9 mm) and supports an industrial temperature range from -40°C to +85°C.

Controllers Feature Summary

• MultiTRAK Technology provides dedicated transaction translators for each downstream port.
• Supports OEM configuration via serial I2C EEPROM or SMBus Slave Port.
• Includes internal 1.8V regulator, power-on reset, and integrated USB termination resistors.
• Features programmable drive strength and differential pair pin location for PCB layout flexibility.

Controllers Applications

• LCD monitors and TVs
• PC motherboards
• Set-top boxes and DVD players
• Printers and scanners
• Mobile PC docking stations

Controllers Procurement Notes

Verify the specific suffix 'JZX' against the manufacturer's official documentation to confirm the commercial temperature grade and tape-and-reel packaging format. Ensure that the ordering information matches the exact datasheet revision required for your design implementation.

Controllers Selection Notes

Select this component when a high-port-count USB hub is required for embedded systems. Consider the industrial temperature rating (-40°C to +85°C) for harsh environments. Verify compatibility with the host controller's upstream interface requirements before finalizing the design.

Controllers Part Context

This part belongs to the USB2517 family of USB 2.0 hub controllers. The 'I' suffix denotes the industrial temperature range variant, while the base model typically covers the commercial range. The JZX suffix indicates the specific package and reel configuration provided by Microchip Technology.

Controllers Replacement Considerations

Check for the USB2517-BXK as a potential alternative if the commercial temperature range is sufficient. Verify pinout and electrical specifications against the original datasheet to ensure functional equivalence in the target application.

Controllers FAQ

How does the USB2517I handle transaction translation?

It uses MultiTRAK technology, which provides one dedicated transaction translator per downstream port to maximize performance.

What are the configuration options available for this hub controller?

Configuration can be performed via an external serial I2C EEPROM, an SMBus Slave Port, or through internal default settings with pin strapping overrides.

Does the device support self-powered operation?

Yes, it includes a VBUS_DET pin to detect upstream power and supports local/self-power sources for downstream ports.
