Reference Information
5. Timing Generator (MN5246)
A timing generator generates each clock, synchronized signal, and CCD driving pulse for the system. Also, it
receives the shutter speed information for the photo-exposure control (from the microprocessor).

6. Analog processing IC (MN2038FAQ)
After eliminating the noise (CDS) from the CCD output signal (which is input to Pin39, to DS1/DS2 signal
of TG), Analog processing IC outputs it to Pin 46, and then it is input to pin 2 through C232 (for Row Clip and
primary amplificationAGC). Then it is output to Pin 35 and Pin 37 of EVR (IC206), which is input to pin 36,
which controls AGC. Pin 35 output signal is input to Pin 26 through C218, and is amplified second time at the
main amplifier. The offset adjust (pin 16 input) is activated by EVR output signal (Pin 4) and the output (Pin 21)
is sent to A/D converter.
