APPLICATIONS INFORMATION
The AD9841A and AD9842A are complete Analog Front End
(AFE) products for digital still camera and camcorder appli-
cations. As shown in Figure 32, the CCD image (pixel) data is
buffered and sent to the AD984xA analog input through a series
input capacitor. The AD984xA performs the dc restoration,
CDS, gain adjustment, black level correction, and analog-to-
digital conversion. The AD984xA’s digital output data is then
processed by the image processing ASIC. The internal regis-
ters of the AD984xA—used to control gain, offset level, and other
functions—are programmed by the ASIC or microprocessor
through a 3-wire serial digital interface. A system timing gen-
erator provides the clock signals for both the CCD and the AFE.
