AN2125FHS
Analog signal processing super single-chip IC for CCD camera
I Overview The AN2125FHS is a super single-chip IC,
working as an image signal processing circuit for CCD camera including Y/C mix, 75-Ω driver, and sub-carrier generation functions as well as luminance signal processing, color difference signal processing functions and an encoder.
Moreover, the AN2125FHS includes auto-whitebalance control circuits, operational amplifiers for AGC, and automatic read-out function from EEPROM at power-on sequence, and DACs for adjustment, therefore a CCD camera system without a microcomputer can be constructed by only additional EEPROM.
I Features • For 510H (250 000 pixels) CCD • NTSC/PAL compatible • On-chip FH lock system (sub-carrier generation) • On-chip automatic read-out function from
EEPROM data at power-on • On-chip DAC for adjustment (8 bits, 32 channels) • On-chip circuit for external synchronization • On-chip comparator for electronic .
