s Overview

The AN2125FHS is a CCD camera video signal pro-

cessor IC featuring luminance and color-difference

signals processing, and encoding, Y/C mixing, 75-

Ω

driver output, and subcarrier generation. It also in-

cludes 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 ex-

ternal EEPROM, you can make all signal processing

system without a microprocessor.

s Features

• Supports 510H CCDs (250,000 pixels)

• Compatible with both NTSC and PAL

• Built-in FH lock system for subcarrier generation

• Built-in automatic EEPROM read-in circuit at power-

on instance.

• Built-in adjustment DAC (8 bits, 32 channels)

• Built-in external synchronization circuit

• Built-in comparator to provide for an electronic iris
