Type-C Technology Overview
The latest versions of USB, DisplayPort (DP), and Thunderbolt leverage the USB Type-C connector for audio/video, data, and power over a single cable. This application note will focus specifically on the USB4 logical layer link over USB Type-C.
The USB4 standard provides 20 Gbps signal rates on each of four transmit and receive lanes with the Type-C connector. USB4 also must support an x2 mode with a bonded bit rate of 40 Gbps in each direction. Even though other high-speed standards have faster data rates, USB4 works with a low-cost cable that yields an 80 Gbps link. Figure 1 shows the signaling lines on a Type-C connector for USB4.
