1.2 Features of the FPD-LINK Interface

FPD-Link (Flat Panel Display Link) is TI's high-speed serializer/deserializer (SerDes) technology, which transmits high-resolution video, audio, control data, and power over a single coaxial cable or twisted-pair wire. Its core value lies in:

  • Simplified Wiring: Reduces the number of cables, harness weight, and connector complexity.
  • Strong Immunity to Interference: Leverages a proprietary protocol to stably transmit audio/video signals and control signals, making it well-suited for the automotive electronic environment.
  • Long-Distance Transmission Support: Reliable transmission over distances of up to 10–15 meters.
  • Flexible Architecture: Enables a "screen-display separation" design, allowing displays and hosts to be physically decoupled.

High-Speed, Low-Latency Transmission: FPD-Link III/IV supports serial data rates of up to 30Gbps, seamlessly transmitting 4K/60fps video data to meet the high bandwidth requirements of ADAS cameras. T

Robust Immunity to Interference: Differential signal transmission and adaptive equalization provide video signal integrity in complex automotive electromagnetic environments, reducing the impact of cable length on image quality.

Simplified Wiring Design: Integrates video, control signals, and power delivery over a single wire (e.g., FPD-Link IV supports power-over-coax), reducing the number and weight of cables and lowering overall vehicle cost.

Functional Capabilities: FPD-Link III and above support video and audio data transmission as well as full-duplex control (e.g., I2C, GPIO) over a single differential link, enabling bidirectional communication. This means that touch inputs, status information, and other data from the display side can be sent back to the host system through the same cable. Functional Safety and EMI: Many FPD-Link SerDes chips are AEC-Q100 certified, with the ability to withstand automotive temperature variations and electromagnetic interference (EMI). They often include adaptive equalization to dynamically compensate for signal degradation caused by cable aging and temperature fluctuations.

Application diagrams of FPD-Link in automotive display and ADAS systems are shown in Figure 1-2 and Figure 1-3.
