Media Agnostic (MA) USBMedia Agnostic (MA) USB

• Allows wireless devices and docking stations to communicate over the USB protocol, without a physical USB connection

• A design goal of MA USB is to achieve wireless gigabit transfer rates while leveraging existing USB infrastructure

• WiGig Serial Extension (WSE) v1.2 specification from the Wi-Fi Alliance® provides the initial foundation

• Multiple media types supported:

• WiGig 60Ghz

• Wi-Fi 2.4 and 5Ghz

• WiMedia UWB radios operating between 3.1 -10.6Ghz,

• Other existing or new media types that want to use USB as the transport

• MA USB will be compliant with:

• SuperSpeed USB (USB 3.0)

• Hi-Speed USB (USB 2.0)

“Inside-the-box” uses

SuperSpeed USB for inside-the-box applications

• Scalable speeds up to 5 Gbps

• Lower voltage/power than external USB 3.0

• Optimized for mobile devices as well as PCs

Physical Layer


Why use SSIC for your mobile product?

1. Enables the logical transition from USB HSIC products for

higher bandwidth with a physical layer optimized for low

power mobile platforms

• Three times bandwidth for same power as HSIC

2. Leverage SuperSpeed USB protocol enhancements and

infrastructure

• Hardware IP, Verification IP, Software OS Support

SSIC specification is now available

Inter-Chip Supplement to the USB Revision 3.0 Specification



• Physical Layer:

• Replace the SuperSpeed USB

PHY with a MIPI M-PHYSM

• PHY Adapter (PA):

• M-PHY Control and

Management

• USB Link Layer:

• LTSSM changes for M-PHY

• USB Protocol and above:

• No changes

• Existing USB SW stack

preserved


Worldwide Shipment of USB-enabled DevicesWorldwide Shipment of USB-enabled Devices


• USB is the most successful interface in the history of PC

• Device charging over USB has become a major consumer feature

• USB installed base is 10+ billion units and growing at 4+ billion units a year

• Shipments will reach roughly 5.1 billion devices by 2018, an increase of over 19% from 2012
