AN2127FHSAnalog signal processor SUPER ONE CHIP IC for CCD camera

OverviewThe AN2127FHS is SUPER ONE CHIP IC of

signal processing circuits for a CCD camera. It in-corporates luminance signal processing, color sig-nal processing and encoder, plus Y/C mix., 75 driver and sub carrier generation circuit. In addi-tion, it incorporates an auto white balance controlcircuit, AGC ope-amp., adjustment DAC andEEPROM auto read circuit at power on, thereby itallows you to constitute a microcomputer systemby just mounting EEPROM.

Features Applicable for 768 H CCD Usable commonly for NTSC and PAL Built in FH lock system (sub carrier generation

circuit) Built in automatic EEPROM read circuit at power

on Built in adjustment DAC (8 bits, 32 channels) Built in a circuit for external synchronization Built in electronic iris comparator

Applications A full range of CCD cameras such as surveillance

camera, board camera, video camera, televisiontelephone, television conference system, PC in-put camera
