USB2514-HZH

Controllers Overview

The USB2514-HZH is a USB 2.0 Hi-Speed Hub Controller IC from the SMSC USB251x family, manufactured by Microchip Technology. It features four downstream ports and operates within an extended commercial temperature range of 0°C to +70°C. The device utilizes a 48-pin QFN package measuring 7 x 7 mm with a height of 0.5 mm. It supports low-speed, full-speed, and high-speed (up to 480 Mbps) data transfers on all enabled downstream ports. The controller includes integrated termination resistors and pull-up/pull-down components, supporting both self-powered and bus-powered configurations.

Controllers Feature Summary

• MultiTRAK technology provides dedicated transaction translators per port for consistent full-speed throughput
• PortMap allows flexible port mapping and disable sequencing for platform design flexibility
• PortSwap enables programmable differential-pair pin locations to simplify PCB routing
• PHYBoost offers four levels of programmable signal drive strength to restore signal integrity

Controllers Applications

• LCD monitors and TVs
• Multi-function USB peripherals
• PC motherboards
• Set-top boxes, DVD players, DVR/PVR
• Printers and scanners

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm package dimensions and temperature ratings. Ensure compatibility with the target system's power requirements and interface protocols before finalizing procurement orders.

Controllers Selection Notes

Select this component when a compact 4-port solution is required in a 48-pin footprint. It serves as a direct drop-in replacement for other USB251x variants sharing the same package, allowing for cost savings through shared PCB components and application compliance.

Controllers Part Context

This part belongs to the SMSC USB251x hub family, which includes controllers with 2, 3, 4, or 7 downstream ports. The 'H' suffix indicates the 48-pin QFN package variant, distinguishing it from the 36-pin and 64-pin options available in the broader product line.

Controllers Replacement Considerations

USB2514B and USB2514Bi are fully footprint compatible and serve as direct drop-in replacements. They utilize the same PCB components and support USB-IF Compliance by Similarity, though PID and DID defaults may differ.
