USB Technology Update
2
The New USB Technologies
• New USB technologies provide a single source for delivering audio/video, data and power simultaneously for every conceivable platform and device
• Key advantages for consumers:
• Performance (speed for all data transfer needs)
• Power (more power for faster charging)
• Convenience (reversible plug orientation and cable direction)

Performance — USB 3.1
• USB 3.1 specification (announced July 2013) absorbed USB 3.0 and added performance boosts to meet requirements for USB storage, display and docking applications
• USB 3.1 Gen 1 (synonymous with USB 3.0)
• Product signals at 5 Gbps
• Market name/certified brand: SuperSpeed USB
• USB 3.1 Gen 2
• Products signal at 10 Gbps
• Market name/certified brand: SuperSpeed USB 10 Gbps
• Possible connectors:
• USB Type-C™ plug and receptacle
• USB 3.0 Standard-A/USB 3.0 Standard-B plug and receptacle
• USB 3.0 Micro-B plug and receptacle
• USB 3.0 Micro-A plug
• USB 3.0 Micro-AB receptacleCONFIDENTIAL | USB Implementers Forum ©2015

Power — USB Power Delivery 2.0
• USB has evolved from a data interface to a primary provider of power
• USB Power Delivery specification (and subsequent v2.0 update announced August 2014) provides more flexible power delivery along with data over a single cable
• Voltage, current and direction can be negotiated without changing cable direction
• Higher voltage and current can deliver power up to 100W
• Upper limit bound by international safety requirements
• Manufacturers can implement USB PD on hosts, hubs, cables and devices
• In order to experience the full user benefits of USB PD, the host, device and cable must support USB PD

Convenience — USB Type-C™
Cable & Connector
• There was an industry need for a new connector to meet the demands of emerging computing platforms
• USB Standard-A was too tall and too wide
• USB Micro-B was designed specifically for mobile phones, not robust enough for larger platforms
• Solution: USB Type-C™
• Redesigned the form factor and used the opportunity to overhaul all aspects of USB and future-proof the technology
• Slim and sleek design enables ultra-thin form factors
• Reversible plug orientation and cable direction solves user confusion
• Scalable power and performance capabilities future-proof the technology
• Alternate Modes enable a truly single-cable solution

USB Type-C™ Alternate Modes
• Permits a vendor or standards organization to utilize USB Type-C™ cable and connector and provide additional features
• Requirements for a standardized Alt Mode:
• Execute liaison agreement with USB 3.0 Promoter Group and USB-IF
• Obtain standard or vendor ID (SVID) from USB-IF
• Standardized Alt Modes available today:
• DisplayPort™ Alternate Mode (Developed by VESA, announced Sept. 2014)
• MHL Alternate Mode (Developed by MHL, LLC, announced Nov. 2014)
• USB-IF has defined joint port identification guidelines to ensure consumers can easily recognize what capabilities a USB Type-C™ host or device supports

USB Type-C™ Market Adoption
and Potential for Market Confusion
• Many cable options will enter the market supporting different performance and power protocols
• USB Type-C (USB 2.0 only performance) cables and connectors
• USB Type-C (USB 3.1 performance) cables/connectors
• USB Type-C Adapters
• USB Type-C to USB Std-A
• USB Type-C to USB Std-B
• USB Type-C to Micro-A, -B, -AB
• USB Type-C to HDMI
• USB Type-C to Displayport, MiniDP
• USB Type-C to MHL
• How will consumers know what a cable can do?

USB-IF Certified Logos
• Products that successfully complete USB-IF certification and sign a logo license agreement can use the certified USB marks to identify the performance and power protocols supported
• Marks on the cable/connector overmold
• Marks on the USB port
• Logos on the product packaging
CONFIDENTIAL | USB Implementers Forum ©20158
USB-IF Certified Logos, cont.
• Existing USB logos will be applied to certified products based on the USB protocols supported
• USB logos on the horizon
• Certified USB Power Delivery
• USB PD Only Device (no data)
• Example: USB PD charger. This type of certified device will be identified by the USB PD original trident icon to indicate USB PD/charging capability
• Original USB + USB PD
• SuperSpeed USB + USB PD
• SuperSpeed USB 10Gbps + USB PD
• Joint Port Identification for Alternate Modes

USB Joint Port Identification Examples
• SS USB 10Gbps/PD + DisplayPort
