What do USB-C cables plug into?
This means that it can be a standard connector for both computers and phones, as well as other devices like game consoles. Some popular devices that use USB-C cables are the Nintendo Switch, MacBook Pro, and Samsung Galaxy line of phones.
What is an Emca cable?
An Electronically Marked Cable Assembly (EMCA) is a USB Type-C cable that uses a marker chip to communicate the cable’s characteristics to the attached devices. Inside these cables is an IC chip that processes the Power Delivery communication protocols.
What does Cable Type-C mean?
USB-C is the emerging standard for charging and transferring data. USB-C features a new, smaller connector shape that’s reversible so it’s easier to plug in. USB-C cables can carry significantly more power, so they can be used to charge larger devices like laptops.
Do USB-C cables have chips in them?
Fully featured USB-C connectors have a tiny chip inside, called a channel configuration (CC) or port controller. A mouse with a USB-C plug will never need blazing speeds, so a USB 2.0-compliant USB-C cable makes sense.
What makes a Type C cable an EMCA?
Type-C Electronically Marked Cable Assemblies (EMCA) are cables that require V CONN power to power the marker electronics inside the cable. These EMCA’s expose R a termination resistors on the V CONN pin of the Type-C plug. Non Electronically Marked Type-C cables do not have electronics inside and have no need for V CONN power.
How is USB Type C used in a cable?
USB Type-C reduces cable clutter and improves ease of use. USB-PD over Type-C adds a delivery sideband communication channel over a new Type-C signal called the configuration channel (CC). The CC wire is used for both USB Type-C V BUS power level notification and it is used for USB-PD negotiation and control.
How does an electronically marked USB cable work?
The electronic marking is accomplished by embedding a USB PD controller chip into the plug at one or both ends of the cable. These marker chips operate from V CONN power (or V BUS power as per the cable design). V CONN is a low voltage rail operating between 2.7 Volts and 5.5 Volts but is limited to 1 Watt of power.
When is Electronic marking necessary in a Type-C cable?
When is Electronic Marking necessary? Electronic marking is needed in a Type-C Cable when any of the following apply: V BUS Current of more than 3 Amps is required USB 3.1 Gen1 or Gen2 is required
