USB Type-C

USB Type-C
USB Type-C
USB Type-C is a USB specification for a small 24-pin reversible connector for USB devices and USB cabling.The USB Type-C specification 1.0 was published by the USB Implementers Forum and was completed in August 2014 It was developed at about the same time as the USB 3.1 specification
The connecting USB Type-C connectors on both hosts and devices, replacing the various Type-B and Type-A connectors and cables with a standard designed to be future-proof. The 24-pin connector both sides is the same as the micro-B connector to a USB port type C measuring 8.4 mm (0.33 in) by 2.6 mm (0.10 in). The connector provides four power / ground pairs, two differential pairs for non-SuperSpeed data (although only one pair is populated into a USB Type-C cable), four pairs for high-speed data bus, two “sideband use “pins and two configuration pins for cable orientation detection, dedicated biphase mark code (BMC) configuration data channel, and UCONN 5 V power supply for active cables. an older device with a USB Type C holder or adapter requires a type A or type B plug or socket on one end and a USB type C plug at the other end. Adapters with USB Type C container “is not defined or permitted” with the specification because of their ability to make “many false and potentially unsafe” cable combination. Full-featured USB Type-C cables are active, electronically marked cables containing a chip with an ID function based on the configuration of the channel and vendor-defined messages (VDM’s) of the USB Power Delivery 2.0 specification. USB Type-C units, if desired, support bus power currents of 1.5 A and 3.0 an (at 5 V) in addition to the baseline power supply bus; power sources may be either advertise USB increased current flow through the channel configuration, or they may be the full power supply specification using both BMC-coded line configuration and legacy BFSK-coded to support VBUS line.
Alternate Mode
An Alternate Mode dedicates a portion of the physical wires in the USB Type-C cable for direct device-to-host transmission of alternative data protocols. The four lanes of high-speed, two pins sideband, and (to the dock, detachable panel, and permanent cable applications) with two non-Super Speed data pins, and one configuration may be used for switch-mode transmission. The modes are configured with VDM’s the configuration channel.
Relative to other specifications
USB-IF specifications
As pointed put by the USB Type-C cable and connector Language Usage Guidelines, as a product implements USB Type-C, it is not necessarily to perform USB 3.1 or USB Power Delivery.
1. USB Type-C Locking Connector Specification
Alternate Mode partner specifications
The USB Implementers Forum is working with its partners Alternate Mode to ensure that the parts are well labelled.DisplayPort Alternate Mode to USB Type-C Connector Standard – published in September 2014, supporting DisplayPort 1.3. MHL Alt Mode announced in November 2014 to support MHL 3.0. Thunderbolt Alternate Mode Supporting Thunderbolt 3. Other serial protocols such as PCI Express and Base-T Ethernet are possible
