The DesignWare® Hi-Speed USB On-The-Go (HS OTG) Controller provides designers with high-quality USB IP for the most demanding USB 2.0 peripherals. Based on Synopsys' success in building and deploying Hi-Speed USB 2.0 Host, Device and PHY designs in over 100 design wins, the DesignWare HS OTG Controller incorporates all Synopsys learning to date in Reuse Methodology, Constrained Random Verification, and USB PHY interoperability to deliver flexible, quality IP in Verilog source.The DesignWare HS OTG Controller performs as a standard Hi-Speed, Dual-Role Device (DRD), operating as either a USB 2.0 Hi-Speed compliant peripheral, or Hi-Speed USB 2.0 host. For example, when HS OTG is implemented in a PDA, the PDA can synchronize with a PC. The PDA can also act as the host printing pictures and documents directly to a USB printer without the aid of a PC. Additional applications include mobile phones, MP3 players, digital cameras, set-top boxes, scanners and fax machines. The DesignWare USB HS OTG Controller delivers a flexible, low gate count USB controller capable of OTG, host and device functions. DesignWare Hi-Speed USB On-The-Go Controller Datasheet
