FPD-Link III serializers and deserializers are used to connect video components of driver assist and infotainment display solutions. The DS90UB901 is used to serialize the RGB inputs from a camera imager in a driver assist system to be sent over long distances on an EMI-friendly single differential pair to the DS90UB902 deserializer. The deserializer then converts the serialized signal back into a parallel RGB signal to be delivered to a display or as a video input to an infotainment system. The DS90UB903 serializer is used in a similar fashion with a video source in an infotainment system to allow long distance transfer of video information. The DS90UB904 deserializer is the matching component that returns the video signal to a parallel RGB video source for use with infotainment displays. The key differences between the two sets of products is that the pair that targets camera systems is limited to a 14-bit color display and has special support to check the validity of data and real time general purpose inputs and outputs (GPIOs) to facilitate camera synchronization, while the pair targeting touch screen displays has support for an 18-bit color display. The diagram on the bottom shows a typical driver assist system and shows where various serializers and deserializers can be used.
