■ Overview

The AN2125FHS is a CCD camera video signal processor IC featuring luminance and color-difference signals processing, and encoding, Y/C mixing, 75-Ω driver output, and subcarrier generation. It also includes an automatic white balance control circuit, an operational amplifier for AGC, a DAC for adjustment, and a circuit that automatically reads the EEPROM at the instance of power-on. Together with only an external EEPROM, you can make all signal processing system without a microprocessor.
