SmartDV’s USB 2.x OTG IP is a silicon-proven, fully featured Universal Serial Bus On-The-Go solution purpose-built for SoC designs requiring flexible, dual-role USB connectivity across mobile, automotive, IoT, and consumer electronics applications. Fully compliant with USB 2.0, USB OTG and Embedded Host Revision 2.0, and USB OTG EH3 Revision 1.0, it delivers a comprehensive USB OTG implementation available in USB 2.0 Embedded Host, USB 2.0 Peripheral Only, and USB 2.0 OTG configurations — supporting High Speed, Full Speed, and Low Speed operation with xHCI-compliant host mode operation at up to 480 Mbps.
Designed to address the full breadth of USB 2.x OTG integration requirements, the IP supports Session Request Protocol (SRP), Host Negotiation Protocol (HNP), and Attach Detach Protocol (ADP) for complete OTG role switching, alongside a proprietary DMA engine for high-efficiency data transfer, configurable endpoint management, 32-bit and 64-bit internal and AXI data paths, and comprehensive root hub features for Embedded Host applications. Its software-configurable speed and HNP/ADP support, optional simple slave mode for area-optimized designs, all USB Link Power Management states L1 and L2, and system power management give SoC teams a production-tested, feature-complete USB 2.x OTG implementation suited for the most demanding mobile and embedded dual-role USB designs.
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 16-bit UTMI+ Level 3 PHY interface, AXI DMA path, AHB register path, and configurable endpoint architecture enable fast integration and confident design bring-up across a wide range of process nodes and target applications.
