Frequently Asked Questions
What USB data rate does the USB2660I-JZX-03 support, and how many downstream ports can it manage?
The USB2660I-JZX-03 operates at USB 2.0 high-speed rates of 480 Mbps on the upstream port and supports multiple downstream ports, typically up to 7 downstream connections depending on configuration. Its integrated transaction translator bridges full-speed (12 Mbps) and high-speed (480 Mbps) devices simultaneously without external components.
What thermal advantage does the 64-pin QFN package with exposed slug provide in compact hub PCB layouts?
The 64-pin QFN package with exposed thermal slug allows direct solder attachment to a PCB copper pour, providing a thermal resistance of typically under 30°C/W junction-to-board. This enables reliable continuous operation in industrial environments where ambient temperatures may reach 85°C, keeping junction temperatures within the safe operating range of the USB2660I-JZX-03.
When is the USB2660I-JZX-03 preferred over a discrete USB switch approach for adding multiple USB ports to an embedded design?
A discrete USB switch approach requires individual switches per port plus external logic for transaction translation, typically adding 3 to 5 ICs and significant routing complexity. The USB2660I-JZX-03 integrates hub controller, transaction translator, and per-port power management in a single 64-pin QFN, reducing BOM by at least 4 components and simplifying firmware to standard USB hub class enumeration.
