This is just odd enough that I'm curious. > I think I missed replying to this. I would guess it is a pair of muxes - but I do not know for sure. The data-sheet I've seen is not too detailed. The "block diagram" I see shows the photo sensors followed by four ADCs. This, however, is just a very rough picture and it does not show the muxes. I guess it is there just to illustrate the functionality more than to really explain the hardware.
