  The CH32X035 Type-C PD display solution can provide a full-featured Type-C port for the display, supporting first-line screen projection functions for mobile phones, computers, game consoles, etc., and also supports PD fast charging output. CH32X035 has a built-in USB Power Delivery controller and PD PHY transceiver, supports fast charging protocols such as PD2.0/3.0, and completes Alternate Mode negotiation and PD fast charging output on a single chip. In addition, CH32X035 supports USB port upgrade and Billboard prompt function, and can be widely used in desktop monitors, portable monitors, etc.
Type-C PD display
  CH32X035: CH32X035 supports PD2.0/3.0, PPS, BC1.2 and other fast charging protocols, and can be used for power management, power receiving end, power supply end, and DRP. Supports USB communication for Billboard window prompts. In the solution, CH32X035 mainly completes PD protocol fast charging, Alternate Mode negotiation and Billboard device simulation.
  CH334: CH334 adopts a multi-port independent parallel MTT structure design. Compared with the multi-port time-sharing STT mode, the USB transmission bandwidth in MTT mode is theoretically increased by 4 times. It is an industrial-grade HUB that supports a -40~85°C temperature operating range and has a higher High ESD characteristics, supporting 6KV, CH334 has higher integration and streamlined peripherals, which can effectively reduce circuit costs.
  CH9445: CH9445F is a differential ultra-high-speed signal bidirectional ana-log switch chip with high bandwidth and low on-resistance. It can be used for switching differential signals up to 10Gbps USB3.1 SuperSpeed Gen2, 8Gbps DP1.4, USB2.0 HighSpeed and other differential signals. It can be used for tablets, laptops, docking stations, USB hosts and devices, etc.
