1 VESA Alt Mode for Type- C Standard Feature Summary Sept 22, 2014

2 VESA Alt Mode Summary The VESA Alt Mode Standard, Version 1, was released on Sept 22, 2014 Enables the use of the Type- C interface for Leverages the Alternate Mode funcgonal extension of the Type- C interface Developed in liaison with the 3.0 Promoter Group 2

3 Introduc:on of Type- C information is provided as an informative overview only, please refer to the Cable and Specification available at for more information New generagon of connector developed to serve the market for next 20 years Thin profile suitable for both ultra portable devices and larger devices Reversible plug orientagon & cable direcgon 3.1 Gen 2 (10Gbps) Power delivery, up to 100 wats Supports Alternate Mode Standard-A will be the only interface you will need High speed, secure data Display connection System Power 3

4 Example Type- C Configura:ons Either end can serve as Host, -PD Power Consumer, and Video Source (these services are orthogonal to each other) Device Charging Device Charging 2.0 or 3.1 Data Display Data Dock Device Supplying Power 2.0 or 3.1 Data Display Data 4

5 Type- C Func:on Extension Alternate Mode Host With Alternate Mode Capability or 3.1 Data to Cable Power Delivery or Device (or Dock) With Alternate Mode Capability A passive Full Feature Type- C to Type- C cable can carry up to four lanes This will offer the same performance and feature capability as a standard connecgon This will also allow data rates to increase in the future, since the Type- C connector has very high data rate capability can be combined with 3.1 operagon over the same Type- C cable Implemented with two high speed pairs for DP (using two lane DP operagon), and two high speed pairs for ( 3.1 only uses two high speed lanes for normal operagon) Useful for docking stagons or hubs, or for adding docking stagon funcgonality to a display 2.0 and Power Delivery is available in all configuragons Because 2.0 and Power Delivery use dedicated wires in the Type- C cable, both of these services are always available, even when using all four Type- C high speed pairs for 5

6 Type- C Receptacle Pins Below is a diagram of the pins defined for system or device receptacle High Speed Data Path (TX for, or for DP Alt Mode) 2.0 Interface High Speed Data Path (RX for, or TX for DP Alt Mode) Cable Ground Cable Bus Power For Sideband Use (not used for ) Plug ConfiguraGon DetecGon One becomes VCONN, for cable or adaptor power CC is used for - PD communicagon 6

7 Type- C Pin Ma:ng Receptacle configuragon Plug configuragon (for cable, or other plug- in device) Plug can inserted into receptacle in either orienta:on (can rotate 180 degrees) Device with receptacle is responsible detec:ng orienta:on and rou:ng proper signals to receptacle pins as needed 7

8 Type- C to Type- C Full Feature Passive Cable Cable SSTX1 SSRX1 SSTX2 SSRX2 2.0 SBU1/2 CC / VCONN VBUS GND ID This will be a common, widely available cable for Type- C applicagons, and it will support the Alt Mode Full Feature Type- C cables and certain adapters have an electronic ID that can be read by - PD protocol to determine capability Passive cables up to 1m are designed to support SS Gen 2 (10 Gbps) Passible cable up to 2m are designed support SS Gen 1 (5 Gbps) 8

9 Type- C Plug Orienta:on Reversing is Supported by a PHY Switch Controller SSTX SSRX SSTX SSRX (Optional) 2.0 Which CC receptacle pin the cable CC wire is connected to is used to determine plug orientation -PD Controller Detect and Config CC VCONN Cable / Adaptor Power Configuration Switch Device-to Device Power (Source or Consumer) SSTX SSRX SSTX SSRX SBU1 SBU2 CC1 CC2 Vbus GND Receptacle Example for Type- C receptacle that supports modes only A similar switch is needed at the Device end Switch can be integrated with funcgon 9

10 Type- C PHY Switch for Suppor:ng Alternate Mode Controller SSTX SSRX SSTX SSRX MUX / Configuration Switch (Signal paths for alternate plug orientations removed to simplify diagram) SSTX SSRX SSTX SSRX Example for interface that supports and Alternate Mode GPU ( Source) (Optional) 2.0 Lane 2 Lane 3 Lane 1 Lane 0 AUX+ AUX SBU1 SBU2 Receptacle Similar switch needed at the Device end Switch can be integrated along with the and funcgons Control HPD/IRQ -PD Controller Detect, Config, & HPD CC, HPD VCONN Cable / Adaptor Power Device-to Device Power (Source or Consumer) CC VCONN Vbus GND 10
