Agreed. It could be a few things but the one thing that you can see clearly is the Analog Devices logo. The PN may be a problem anyway since the parts may have a special PN just for Canon. Semiconductor companies often times play games with part numbering. For example they may have a catalog part at a given price, they may offer that same part (possibly with a different pinout and some features killed or not tested) to someone like Canon (in large volume, at a significantly lower price) but mark it differently. That "different" PN may not appear in any catalog. FWIW: I come from the semiconductor business (now retired). That part bears a resemblance to a 10 channel part that AD makes.
Yes I can definately make out their logo and have familiarity with custom semicon parts (I’m currently struggling with finding alternate sources for some RF PA dies; and everyone has their own PN mapping to my spec).
If I squint real hard it looks like there are 14 pins coming off that blue flex. It would kinda sorta make sense if it were carrying digital values (14-bit registers) into a logic device (Analog makes gate arrays, etc). Additionally, I’d expect differential pairs for the analog signal (probably LVDS), and those traces don’t look length-matched.
It’s impossible to tell, but I’m guessing those discrete components adjacent to it are little 0201 resistors to bias the chip.
If it’s an ACD, how do you think it works? How do they buffer the sensor output such that they can write it in blocks of 14 over the cable and into Analog’s part? Clock signal generated on the main board which synchronizes some analog buffers on the sensor board to the ADC?
Note: whatever they are doing seems to work fine, this is just personal curiosity.
@David Hull and @3kram5d ...guys with your line of expertise (semi conductors/electronics) should team up with Roger Cicala at lensrentals.com .. it would give us even better tear-downs! (seriously).
I can speak fairly intelligently to the electronics packaging design, i.e. the chassis, how the boards are configured, cables, mechanisms, thermal management, etc.
When it comes to circuit level stuff (schematic, like we’re discussing here) I probably know more than many purely due to professional interactions, but I’m not an electrical engineer. Of course, when I look at other people’s designs I usually come away with more questions than conclusions
