SYSTEM OVERVIEW
Figure 1 shows the typical system block diagram for the AD9991
used in Master mode. The CCD output is processed by the
AD9991’s AFE circuitry, which consists of a CDS, VGA, black
level clamp, and A/D converter. The digitized pixel information
is sent to the digital image processor chip, which performs the
postprocessing and compression. To operate the CCD, all CCD
timing parameters are programmed into the AD9991 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 AD9991 generates all of the CCD’s hori-
zontal and vertical clocks and all internal AFE clocks. External
synchronization is provided by a SYNC pulse from the micropro-
cessor, which will reset internal counters and resync the VD and
HD outputs.
Alternatively, the AD9991 may be operated in Slave mode, in
which VD and HD are provided externally from the image pro-
cessor. In this mode, all AD9991 timing will be synchronized
with VD and HD.

The H-drivers for H1–H4 and RG are included in the AD9991,
allowing these clocks to be directly connected to the CCD.
H-drive voltage of up to 3.3 V is supported. An external V-driver
is required for the vertical transfer clocks, the sensor gate pulses,
and the substrate clock.
The AD9991 also includes programmable MSHUT and
STROBE outputs, which may be used to trigger mechanical
shutter and strobe (flash) circuitry.
Figures 2 and 3 show the maximum horizontal and vertical
counter dimensions for the AD9991. All internal horizontal and
vertical clocking is controlled by these counters to specify line
and pixel locations. Maximum HD length is 4095 pixels per line,
and maximum VD length is 4095 lines per field.
