In summary, the advantages of Texas Instruments' FPD Link III products – DS90UB901/02/03/04 were highlighted in this presentation. The key takeaway to learn from this product training module is how bidirectional control works.  The idea is that both the video and the I²C bidirectional controller are on the same link. Also important is the approach that is unique to TI, the continuous communication in both directions. What this brings is low latency for both the bidirectional control and for GPIO transmissions. This solution meets the EMI requirements that are crucial in automotive applications. The advantage of being able to put all of these capabilities into one wire pair is that it reduces the cost and weight of the cable harness, which is an important part of the system. This technology is also not dependent on blanking periods. This is important because both GPIO signals and control signals are continuously sent from the system host controller to the remote device, and allows a continuous quick stream of I²C control data to happen. If video blanking was needed, it would slow down the transactions and would limit the timing of the control signals that could be set to the remote devices. This is especially critical in camera systems where multiple cameras need to be synchronized. Lastly, FPD-Link III is based on a broad family of automotive-grade chipsets with support for multiple resolutions, color depths and applications. Driver assistance application-specific chipsets are available that validate data for high reliability in safety critical applications. The entire family of FPD-Link II and FPD-Link III parts are based on proven automotive EMI solutions and do not require any software drivers, thereby reducing the complexity of designing automotive systems.
