Core Features & Advantages
The USB2514B-AEZC-TR delivers a 4-port USB 2.0 Hi-Speed hub controller with per-port MultiTRAK transaction translators and USB Battery Charging 1.1 support in a compact 6 x 6mm VQFN-36 package.
- Primary Function: 4-port USB 2.0 Hi-Speed hub controller IC that expands a single upstream USB 2.0 port into 4 downstream ports with MTT (multi-transaction translator) architecture for maximum throughput in mixed-speed environments.
- Advantages:
- MultiTRAK MTT architecture (1 TT per port) — each downstream port has a dedicated transaction translator, preventing the bandwidth bottleneck of single-TT hubs when multiple full-speed devices are connected simultaneously.
- PHYBoost 4-level programmable drive strength — adjustable USB signal drive strength compensates for PCB trace length and connector quality variations, recovering signal integrity without external redriver chips.
- PortMap + PortSwap pin flexibility — programmable port mapping and USB differential-pair pin swap enable direct PCB routing from hub to connectors without crossover traces, simplifying layout and reducing EMI.
Typical Application Scenarios
- Industry: Consumer / Computing / Industrial / Automotive
- Equipment: LCD monitors/TVs, PC motherboards, docking stations, set-top boxes, printers, gaming consoles
- Use Cases:
- Embedded USB hub in LCD monitors expanding 1 upstream port to 4 downstream ports for keyboard, mouse, webcam, and USB storage with BC 1.1 phone charging.
- Industrial PLC USB port expansion with MTT ensuring full-speed devices (HID, serial adapters) do not degrade hi-speed device throughput on adjacent ports.
- Automotive infotainment USB hub with PHYBoost compensating for long cable runs to rear-seat USB ports in vehicle head unit designs.
