APPLICATIONS INFORMATION
The AD9824 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 AD9824 analog input through a series input capacitor.
The AD9824 performs the dc restoration, CDS, gain adjust-
ment, black level correction, and analog-to-digital conversion.
The AD9824’s digital output data is then processed by the
image processing ASIC. The internal registers of the AD9824—
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.
