There are three simple things to keep in mind.
- Are they GMSL compatible? (i.e. Same GMSL1 mode, at 3Gbps link speed)
- Is the video input/output compatible? (i.e. RGB888 in, and RGB88 out)
- Are they compatible in the side features that you are trying to use? (i.e. serializer supports passthru I2S, as well as deserializer)
