2.1.2 Data Flow Pipeline

The radar data generated by the AWR2188 is transmitted via the FPD-Link IV serializer, which converts the CSI2 data output from the AWR2188 into serialized data. This data is transmitted over FAKRA cabling to the UB9702 deserializer. The deserializer converts the serial data back to CSI-2 format and forwards it to the Orin's CSI-2 camera interface, where it appears as a V4L2 video device within the Orin's Linux system.
