Parameter specification of TYPE-C connector

TYPE-C connector is a relatively new standard, which aims to provide high-speed data transmission up to 10Gb/s and power flow up to 100W W. These functions can make USB Type-C a truly universal connection standard for modern devices. It has a reversible connector. The interface is designed so that the plug can be turned over relative to the socket. It supports USB 2.0, USB 3.0 and USB 3.1 Gen 2 standards. In addition, it can also support third-party protocols such as DisplayPort and HDMI in an operation mode called standby mode. It allows devices to negotiate and select the appropriate power flow through the interface.

Power transmission technology makes USB Type-C more universal than the old standard, because it adapts the power level to the needs of the load. You can use the same cable to charge your smartphone and laptop. The RX and TX pins have two sets of RX differential pairs and two sets of TX differential pairs.

One of the two RX pairs and the TX pair can be used for the USB 3.0/USB 3.1 protocol. Because the connector is reversible, it is necessary for the multiplexer to correctly reroute the data on the adopted differential pair through the cable. Please note that USB Type-C port can support USB 3.0/3.1 standard, but the minimum feature set of USB Type-C does not include USB 3.0/3.1. In this case, the RX/TX pair is not used for USB 3.0/3.1 connection, and it can be used by other USB Type-C functions, such as standby mode and USB power supply protocol. These functions can even take advantage of all available RX/TX differential pairs. CC1 and CC2 Pins These pins are channel configuration pins. They perform many functions, such as cable connection and removal detection, socket/plug orientation detection and current advertising. These pins can also be used for communication required by Power Delivery and Alternate Mode.

If the TYPE-C connector is designed according to the industry standard of USB Association, it must be stylish, slim and compact, suitable for mobile devices, and at the same time, it needs high strength to meet the requirements of the Association, and it is also suitable for various industries. USB Type-C connector provides a reversible plug-in interface; The socket can be inserted from any direction to realize easy and reliable plug-in. The connector also needs to support a variety of different protocols, and can be backward compatible with HDMI, VGA, DisplayPort and other connection types from a single C-type USB port by using the adapter. For electromagnetic interference （EMI） and other harsh environments, more designs are needed to meet the requirements.
