Schematy są ale można wysilić się i zrobić kolorowy skan i o większej rozdzielczości. Wtedy schematy płytek będą czytelniejsze. Całość super jako wartość merytoryczna. Wszystkie dane potrzebne do podłączenia różnego rodzajów urządzeń takich gramofon, CD itd.
jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.

5. Transfer of Electric Charge by the Horizontal CCD The transfer system for the horizontal CCD emplays a 2-phase drive method.
VAA11701-R.3571.A
The electric charges sent to the final stage of the horizontal CCD are transferred to the floating diffusion, as shown in Fig. 1-6. RG is turned on by the timing in (1), and the floating diffusion is charged to the potential of PD. The RG is turned off by the timing in (2). In this condition, the floating diffusion is floated at high impedance. The H1 potential becomes shallow by the timing in (3), and the electric charge now moves to the floating diffusion. Here, the electric charges are converted into voltages at the rate of V = Q/C by the equivalent capacitance C of the floating diffusion. RG is then turned on again by the timing in (1) when the H1 potential becomes deep. Thus, the potential of the floating diffusion changes in proportion to the quantity of transferred electric charge, and becomes CCD output after being received by the source follower. The equivalent circuit for the output circuit is shown in Fig. 1-7.

6. Lens drive block 6-1. Shutter drive The lens driver IC (LB8649FN) is used to drive by the two shutter drive signals (SIN1, SIN2) which are output from the ASIC expansion port (IC106), and the shutter is opened and closed. 6-2. Focus drive The focus stepping motor drive signals (FIN1, FIN2, FIN3
and FIN4) which are output from the ASIC expansion port (IC106) are used to drive by the lens driver IC (LB8649FN). Detection of the standard motoring positions is carried out by means of the photointerruptor (FPI) inside
the lens unit. 6-3. Zoom drive The zoom stepping motor drive signals (ZIN1, ZIN2, ZIN3 and ZIN4) which are output from ASIC (IC102) are used to drive by the lens driver IC (LB8649FN). Detection of the standard zoom positions is carried out by means of photoreflector (ZPI) inside the lens unit. 6-4. Iris drive The iris motor drive signals (IIN1 and IIN2) which are output from the ASIC (IC102) are used to drive the lens driver IC (LB8649FN).
