USB 3.1 HUB Controller – Description


USB 3.1 Hub controller is a highly configurable core and implements the USB 3.1 Hub functionality that can be interfaced with third party USB 3.1PHY’s. USB3.1 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 and Hypertransport.

The Pravega Hub Controller core can be configured to support upto 15 downstream ports. The Pravega Hub Controller core supports all defined USB 3.1 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 3.1 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.
