What are the key features of USB2514B?
- 4-port USB 2.0 Hi-Speed hub controller supporting 480 Mbps data rate with per-port transaction translator
- Integrated USB 2.0 compliant PHY with internal oscillator option reducing external component count
- SMBus/I2C interface for runtime configuration of VID/PID and hub descriptors without external EEPROM
What is USB2514B used for?
The USB2514B is widely used in embedded computing platforms such as single-board computers and industrial PCs where multiple USB peripherals must share a single root port. It is integrated into docking stations, USB hubs, and printer/MFP designs requiring compliant Hi-Speed port expansion. Its per-port transaction translator makes it ideal for mixed full-speed and high-speed device environments in factory automation and medical equipment.

Frequently Asked Questions
How many downstream ports does USB2514B support, and what USB speed does each port operate at?
USB2514B supports 4 downstream USB 2.0 ports, each capable of operating at 480 Mbps Hi-Speed, 12 Mbps Full-Speed, or 1.5 Mbps Low-Speed. Each port has its own dedicated transaction translator, allowing simultaneous Full-Speed and Hi-Speed transfers across all 4 ports without bandwidth contention.
Can USB2514B be configured without an external EEPROM for custom VID and PID in production?
Yes, USB2514B supports configuration via an SMBus/I2C interface at up to 400 kHz, allowing a host microcontroller to write VID, PID, and hub descriptors at runtime. This eliminates the need for an external EEPROM in many designs, reducing BOM cost and PCB area by at least 2 components per hub instance.
In a docking station design, what QFN package dimensions should be allocated for USB2514B on the PCB layout?
USB2514B is available in a 36-pin QFN package measuring 6 mm x 6 mm with 0.5 mm pitch. For a compact docking station PCB, reserve approximately 7 mm x 7 mm of board area including bypass capacitor placement, and route differential USB pairs with 90 ohm impedance for compliant signal integrity at 480 Mbps.
