Technical Details & Description

The Microchip USB2517-JZX is a USB 2.0 7-port hub controller in a 64-QFN package. It handles the upstream port and seven downstream ports, managing enumeration, speed negotiation, and power switching for each port.

USB 2.0 only — not a USB 3.0 part

This controller is USB 2.0 (480 Mbps) only. It does not support USB 3.0 SuperSpeed signaling. If your design requires USB 3.0 downstream ports, you need a different hub controller such as the Microchip USB5744 or a USB 3.x hub. The USB2517-JZX is the right choice when all downstream devices are USB 2.0 or 1.1, keeping BOM cost and power lower than a USB 3.0 hub.

ROHS3 compliance is confirmed.

Package and thermal: 64-QFN with exposed pad

The 64-VFQFN package measures 9x9 mm with an exposed pad underneath. Layout should follow the manufacturer's recommended footprint for the 64-QFN (9x9) to ensure proper solder joint reliability.

Frequently asked questions

What is the difference between USB2517-JZX and USB2517-JZXT?

The USB2517-JZX ships in Tray packaging, while the USB2517-JZXT variant ships in Tape & Reel. The silicon and electrical specifications are identical. Choose the JZXT for automated pick-and-place assembly lines that require reel-fed components.

Does USB2517-JZX support USB 3.0?

No. The USB2517-JZX is a USB 2.0 hub controller and does not support USB 3.0 SuperSpeed signaling. It is designed for USB 2.0 (480 Mbps) and USB 1.1 (12 Mbps) downstream devices.

Does USB2517-JZX require an external crystal?

The evidence does not specify an external crystal requirement. Typical USB hub controllers in this family integrate the oscillator circuitry, but you should verify the exact clocking scheme from the full datasheet before finalizing the BOM.

What is the USB2517-JZX used for?

It is a USB 2.0 7-port hub controller used to expand a single USB host port into seven downstream ports. Common applications include PC motherboards, docking stations, KVM switches, and embedded systems that need multiple USB 2.0 device connections.
