The MAX9217/MAX9218 serializer and deserializer chipset has been used for video data transmission with a single twisted-pair LVDS link in automotive and industrial applications. Video signals always have blanking periods in every displayed frame. One can use those blanking periods to ‘piggyback’ audio data. In this application note, we discuss the audio data transmission format, an approach for sending the data over the video link, and an example of system implementation.
