LAN9514-JZX

Controllers Overview

The LAN9514-JZX is a high-performance Hi-Speed USB 2.0 hub integrated with a 10/100 Ethernet controller, manufactured by Microchip Technology. It features four downstream and one upstream USB port, utilizing an integrated USB 2.0 hub architecture with dedicated Transaction Translators for each downstream port. The device includes an IEEE 802.3 compliant 10/100 Ethernet MAC and PHY supporting full-duplex operation and HP Auto-MDIX. Power management capabilities include three suspend modes (SUSPEND0, SUSPEND1, SUSPEND2) and support for bus-powered or self-powered configurations via external switches. The component operates within commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges.

Controllers Procurement Notes

Verify the specific suffix JZX against official datasheets to confirm package type and environmental rating. Confirm RoHS compliance status as some variants may differ. Ensure the ordering information matches the exact silicon revision required for your design. Cross-reference the manufacturer's latest documentation for any recent product change notifications affecting this part number.

Controllers Selection Notes

Select this component when a combined USB hub and Ethernet solution is required to minimize bill of materials. Consider the integrated nature of the PHY and MAC which reduces external component count. Evaluate the power management features if low-power suspended states are critical. Verify that the available GPIOs and LED indicators meet the system interface requirements.

Controllers Part Context

The LAN9514/JZX belongs to the LAN9514 family of USB/Ethernet controllers. This series is designed to provide cost-effective connectivity solutions by integrating multiple functions into a single chip. It targets applications requiring both USB expansion and network connectivity without the need for separate discrete components.

Controllers Replacement Considerations

Consult the manufacturer's official documentation for confirmed substitute part numbers. Ensure any replacement maintains compatibility with the existing USB and Ethernet protocols. Verify pinout and electrical specifications match the original design requirements.
