17   The IMI D&D RDACM20 and RDACM21 are GMSL-compatible camera designed for
20   The RDACM20 camera module encloses a Maxim Integrated MAX9271 GMSL serializer,
21   coupled with an OV10635 image sensor and an embedded MCU. Both the MCU and
22   the image sensor are connected to the serializer local I2C bus and are
25   The RDACM21 camera module encloses the same serializer, coupled with an
26   OV10640 image sensor and an OV490 ISP. Only the OV490 ISP is interfaced to
27   the serializer local I2C bus while the image sensor is not accessible from

47   Both camera modules serialize video data generated by the embedded camera
48   sensor on the GMSL serial channel to a remote GMSL de-serializer. They also
55   propagated to the remote de-serializer encapsulated in the GMSL control
59   deserializer's I2C bus corresponding to the GMSL link that the camera is
