HA118144AF

HA118144AF Video Camera CDS/AGC IC Description The HA118144AF is a bipolar IC that wa s developed to perform the analog signal processing between the CCD and the ADC in a CCD camera, and is optimal for use in CCD camera digital signal processing systems. Features Excellent suppression of CCD output lower frequency noise by using clamp-type correlated double sampling. A high S/N ration by using dual (pre- and post-) AGC amplifi e rs and high sensitiv i t y based on increased coverage. Provides compensation for IC variations and imaging device sensitivity variations with an 8 state gain select circuit. Allows the AGC, gain select, and knee control to be controlled from the system microprocessor over a serial interface. Functions Correlated double sampling AGC Sample and hold Gain select Knee processing Serial interface control 1 HA118144AF Pin Arrangement HA118144AF 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 13 14 15 16 17 18 19 20 21 22 23 24 NC SCK SDATA NC INJECT NC SP1 SP2 GND1 NC VDC NC NC KNP CND4 NC CP NC VCLM CLM SO2 SO1 GND9 NC 1 2 3 4 5 6 7 8 9 10 11 12 NC SIN NC VFB1 VCC1 VCC2 VAGC SOA1 SIA2 VFB2 NC S/N 2 NC VCC9 SPRE NC GND3 NC OSC VCC3 BLK OBP GND2 NC HA118144AF (top view) HA118144AF Pin Functions Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 Pin Name NC KNP GND4 NC CP NC VCLM CLM SO2 SO1 GND9 NC NC VCC9 SPRE NC GND3 NC OSC Oscillator correction 1.7 V DC 5k GND for IIL 0V VCC for 9 V Signal...
