AN2125FHS
NTSC/PAL signal processor IC for 510H color CCD camera
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-
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.
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
