The Synopsys DesignWare® USB Hub (UH01) is a set of synthesizable building blocks that ASIC/ FPGA designers can use to implement a complete USB Hub. The UH01 device is fully compliant with the USB 1.1 specification. By utilizing Synopsys' production-proven UH01 product, designers can significantly reduce development time and engineering risk, and bring USB-based solutions to market faster. The RapidScript® utility enables designers to easily configure the device by setting the number of downstream ports. UH01 is available in Verilog, facilitating synthesis into any ASIC/FPGA technology.DesignWare USB 1.1 Hub Controller Datasheet
