Agamem Microelectronics Inc. PRELIMINARY AA88048 CCD SIGNAL PROCESS & DIGITAL INTERFACE IC DESCRIPTION The AA88048 is a CMOS single-chip signal processing IC for CCD area sensors which includes correlated double sampling circuit (CDS), clamp circuit, programmable gain amplifier (PGA), reference voltage generator, black level detection circuit, 18 MHz 10-bit analog-to-digital converter (ADC), timing generator for internally required pulses, and serial interface for internal function control and PGA gain control, FEATURES •Low power consumption: 80 mW (TYP.) Wide gain range: 1.94 to 36 dB (Gain step: 0.047 dB/step) High speed sample-and-hold circuits: pulse width 11 ns (MIN.) Independent CDS and PGA gain control CDS : –1.94/0/6/12 dB PGA: 0 to 24 dB Black level canceller Settling target: 16 to 127 LSB Capable of independent input of ADC conversion clock and data output clock Power down mode: less than 1 mW Built-in serial interface 10-bit ADC operating up to 18 MHz DNL: ±0.6 LSB (TYP.) Maximum input level of CCD signals: 1.1 Vp-p Accepts a direct signal input to ADC or PGA (input level: 1.0 Vp-p (TYP.)) Single 2.7 to 3.6 V power supply Package: 48-pin QFP* (P-QFP048-0707) 0.5 mm pin-pitch BLOCK DIAGRAM 6+5 6+& 021287 &/3&$3 %$1'*$3 95() &/3&$3 &&'&$3 &&' 5(),1 3*$ 528*+ 6+ G% 287&. 9&20 3*$),1( %,7 $'& &&',1 G% $'&/3 WRG% G%67(3 951 '2 WR'2 $9'' $9'' $',1 2%&$3 '$& $,6(7 &203$5( 7,0,1* *(1(5$725 %/. 2%3 &&'&/3 ©Copyright Agamem Microelectronics Inc. 6(5,$/ 5(*,67(5 $'&/3 6&1 %/$&./(9(/ 5(*,67(5 6&. 6'$7$ 1 $9'' $9'' $966 2%3 $'&. 5(6(71 67%<1 $966 $966 $966 287&. www.agamem.com.tw 2009/03/24 Ver 1.0 AGAMEM MICROELECTRONICS INCOPERATION RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
