First thing to do is identify used chips. Open the box and find out 3
biggest chip. There may be 1, 2 or 3 big chips depending on
integration level.
OK, my Nikon's charger is somewhere, so I have to transcribe what I see ...
On the back of the PCB we have a package with 8 pins, labeled C02H
P26XOD - looks like an EEPROM, Google says. [1]
On the front we have one big RTL2836BU C2K84A1 GC10 [2], and one smaller
FC0013 C1236 0035L. There are two packages with metal enclosure saying
NTK 27.000F, I guess XTALs.
Hope this helps ...
Yeah, that quite enough.
RTL2836BU is USB interface and demod integrated to one package
FC0013 is RF tuner
Xtal freq sounds a little bit unusual compared to those used for DVB-T
sticks.
Biggest challenge is to make driver for the demod. USB interface could
be just same which is used for RTL2831U/RTL2832U even lsusb looks
different. If it is different then new USB interface driver is also
needed. FC0013 driver exists. I am not going to work that one device!
