GDA Universal Serial Bus 3.0 Hub Controller
GDA's USB 3.0 Hub controller is a highly configurable core and implements the USB 3.0 Hub functionality that can be interfaced with third party USB 3.0 PHY’s. USB3.0 Hub controller core is part of USB3.0 family of cores named “Pravega”. The core leverages GDA’s design expertise from its high speed interconnect family of IP’s including PCI Express, Serial RapidIO.

The Pravega Hub Controller core can be configured to support upto 15 downstream ports.
The Pravega Hub Controller core supports all defined USB 3.0 power states. The design is carefully partitioned to support standard power management schemes. Optionally, it can be configured to manage power mode transitions of the controller and the USB 3.0 PHY for aggressive power savings required for bus powered hubs.
The controller's simple, configurable and layered architecture is independent of application logic, PHY designs, implementation tools and, most importantly, the target technology. GDA solution allows the licensees to easily migrate among FPGA, Gate array and Standard cell technologies optimally. Its flexible backend interface makes it easy to be integrated into wide range of applications.
