7. A/D converter (KAD0228) and DRAM Controller (SMA9606)
A/D converter converts the analog signal which is output from Analog processing IC to the 8-bit digital signal
(24.54Mhz). DRAM Controller is synchronized with Vsync, converts the 8-bit data which is output from A/D
converter to 16-bit data, and stores it in DRAM (controlled by the 32-bit microprocessor).
