AD9929
SYSTEM OVERVIEW
Figure 7 shows the typical system block diagram for the
AD9929. The CCD output is processed by the AD9929’s AFE
circuitry, which consists of a CDS, VGA, black level clamp, and
an A/D converter. The digitized pixel information is sent to the
digital image processor chip, which performs post-processing
and compression. To operate the CCD, all CCD timing para-
meters are programmed into the AD9929 from the system
microprocessor through the 3-wire serial interface. From the
system master clock, CLI, provided by the image processor or
external crystal, the AD9929 generates all of the CCDs hori-
zontal and vertical clocks and all internal AFE clocks. External
synchronization is provided by a SYNC pulse from the
CCD

microprocessor, which resets internal counters and resyn-
chronizes the VD and HD outputs.
The H-drivers for H1 to H2, and RG are included in the
AD9929, allowing these clocks to be directly connected to the
CCD. An H-drive voltage of up to 3.6 V is supported. The
AD9929 also includes the CCD vertical driver circuits for
creating the V1 to V4, and SUBCK outputs that allow direct
connection to the CCD. The AD9929 also provides program-
mable MSHUT and STROBE outputs, which may be used to
trigger mechanical shutter and strobe (flash) circuitry.
