Usb Type C Otg Cable Pinout

The usb device that uses full speed bandwidth devices must have a twisted pair d and d conductors.

Usb type c otg cable pinout.

I have been in the market for an otg cable otherwise known as a host cable for some time and i have found that the only places that seem to sell them are online only. The 24 pin double sided connector provides four power ground pairs two differential pairs for usb 2 0 data bus though only one pair is implemented in a usb c cable four pairs for superspeed data bus only two pairs are used in usb 3 1 mode two sideband use pins v conn 5 v power for active cables and a configuration pin for cable orientation detection and dedicated biphase mark code bmc configuration data channel. Charge its battery as well as act as a usb host. Since the connector is flippable a multiplexer is required to correctly re route the data on the employed differential pairs through the cable.

The data is transferred through the d and d connectors while vbus and gnd connectors provide power to the usb device. The 24 pin double sided connector provides four power ground pairs two differential pairs for usb 2 0 data bus though only one pair is implemented in a 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 vconn 5 v power for active cables. Usb otg adapters hubs and card readers when an otg enabled device is connected to a pc it uses its own usb a or usb type c cable typically ending in micro b usb c or lightning plugs for modern devices. Note down all the color of the cable and where it is connected to the actual usb connector on a page.

Usb c formally known as usb type c is a 24 pin usb connector system with a rotationally symmetrical connector. The id pin can also have a 124 kω impedence to ground see below. Usb a b 2 0 and 3 0 cable pinout. This will tell the otg device that it is allowed to draw current off vcc e g.

This is not a problem half the time. This will tell the otg device that it can not charge and hence must supply current to vcc but should act as a usb host. Note that a usb type c port could support usb 3 0 3 1 standards but the minimum feature set of usb type c doesn t include usb 3 0 3 1. The usb cable provides four pathways two power conductors and two twisted signal conductors.

First of all find out the type of usb connector used in the cable. I tend to do a fair amount of online shoppin. It was developed at roughly the same time as the usb 3 1 specification. The usb type c specification 1 0 was published by the usb implementers forum usb if and was finalized in august 2014.
