SmartDV’s USB 2.x Hub IP is a silicon-proven, fully featured Universal Serial Bus hub solution purpose-built for SoC designs requiring reliable, standards-compliant USB hub functionality across embedded, automotive, IoT, and consumer electronics applications. Fully compliant with USB 2.0, it delivers complete hub functionality supporting High Speed and Full Speed operation via 8-bit and 16-bit UTMI/ULPI interfaces, with both Single Transaction Translator (STT) and Multiple Transaction Translator (MTT) support — providing a proven, production-ready USB hub implementation for the most demanding embedded SoC designs.
Designed to address the full breadth of USB 2.x hub integration requirements, the IP supports Bulk, Control, Isochronous, and Interrupt transfers, dedicated control endpoint zero, configurable dual port RAM shared between endpoints, optional PIO mode for interrupt endpoints, downstream device connect and disconnect detection, and USB Suspend/Resume with Remote Wakeup. Its Link Power Management support, comprehensive test mode features, system bus Master/Target clock support, and complete error detection and handling give SoC teams a production-tested, spec-complete USB 2.x hub implementation that integrates cleanly with the widest range of USB host controllers and downstream devices.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its configurable endpoint architecture, UTMI/ULPI transceiver interface support, and clean host interface enable fast integration and confident design bring-up across a wide range of process nodes and target applications.
