An attempted to build the Hamamatsu S6986 Light Modulation Photo IC from commonly available discrete components.
sketchy photodiode front ends and detector circuit as per discussion (LTSpice simulation files and component models). For practical applications consider CLC425 / AD8000. May not work with photovoltaic mode configuration / may not work without VCC/2 virtual ground

I've added a link to the fantastic Light Modulation IC reference from Hamamatsu (hosted on pobot.org), this is the guide which I'm designing my circuit against.
I've also published the KiCad project and schematic files for my work so far. Bear in mind there is a lot of hand wavyness going on for several reasons.
Firstly I haven't put much consideration into component selection as I'm starting by trying to flush out as much of each stage as I can. So the components in each stage are not likely to be ideal.
Other very vague parts include the LED Driver block, the "D" and "U" signals as I don't have a complete understanding of how these stages work yet.
