12-Bit CCD Signal Processor with  
Precision Timing Core  
AD9949  
FEATURES  
GENERAL DESCRIPTION  
New AD9949A supports CCD line length > 4096 pixels  
Correlated double sampler (CDS)  
The AD9949 is a highly integrated CCD signal processor for  
digital still camera applications. Specified at pixel rates of up to  
36 MHz, the AD9949 consists of a complete analog front end  
with A/D conversion, combined with a programmable timing  
driver. The Precision Timing core allows adjustment of high  
speed clocks with < 600 ps resolution.  
0 dB to 18 dB pixel gain amplifier (PxGA®)  
6 dB to 42 dB 10-bit variable gain amplifier (VGA)  
12-bit, 36 MSPS analog-to-digital converter (ADC)  
Black level clamp with variable level control  
Complete on-chip timing driver  
The analog front end includes black level clamping, CDS,  
PxGA, VGA, and a 36 MSPS, 12-bit ADC. The timing driver  
provides the high speed CCD clock drivers for RG and H1 to  
H4. Operation is programmed using a 3-wire serial interface.  
Precision Timing™ core with < 600 ps resolution  
On-chip 3 V horizontal and RG drivers  
40-lead LFCSP package  
APPLICATIONS  
Digital still cameras  
High speed digital imaging applications  
Packaged in a space-saving, 40-lead LFCSP package, the  
AD9949 is specified over an operating temperature range of  
−20°C to +85°C.
