APPLICATIONS INFORMATION
The AD9845A is a complete Analog Front End (AFE) product
for digital still camera and camcorder applications. As shown in
Figure 32, the CCD image (pixel) data is buffered and sent to
the AD9845A analog input through a series input capacitor.
The AD9845A performs the dc restoration, CDS, gain adjust-
ment, black level correction, and analog-to-digital conversion.
The AD9845A’s digital output data is then processed by the
image processing ASIC. The internal registers of the AD984x—
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 generator provides the
clock signals for both the CCD and the AFE.
