USB4 conversion chip
  The USB4 terminal device conversion chip provides both USB and DisplayPort functions, and can still achieve full performance when used with Thunderbolt4 or USB4 systems.
  The biggest feature of USB4 is that the transmission speed is faster, it supports more transmission protocols, uses a Type C interface, is compatible with Thunderbolt 3, and supports 8K@60fps transmission. The popularity of USB4 will have a great impact on the form of terminal equipment. There will be fewer and fewer interfaces, and the form will be highly unified, which means the compatibility will be better.
USB4 conversion chip
  The USB4 conversion chip has a USB4 or Thunderbolt 4 uplink interface, 5 downlink interfaces and 1 DP interface. The DP interface supports 32.4Gbit/s bandwidth and supports up to 8K/60Hz HDR video output. The hardware supports the security function of digitally signed firmware, supports PWM driving LED indicators, and supports firmware upgrades through the USB interface or I2C bus. The USB port supports charging protocols such as BC1.2, Apple2.4A, and Sam-sung, and can charge connected devices. Built-in USB3.2 hub, supports four USB3.2 and one USB2.0 interface, and also supports one DP1.4a interface. The DP interface can also be converted into an HDMI interface through other adapter chips, and can be used with Weifeng VL103, VL105 and other chips for PD support, which can realize the USB-C port power supply, USB interface and display interface expansion of the laptop.
