VERTICAL TIMING GENERATION
The AD9925 provides a very flexible solution for generating
vertical CCD timing and can support multiple CCDs and dif-
ferent system architectures. The vertical transfer clocks XV1 to
XV8 are used to shift each line of pixels into the
ut register of the CCD. The AD9925 allows these outputs to be
individually programmed into various readout configurations,
sing a 4-step process.
u
Figure 30 shows an overview of how the vertical timing is gen-
erated in four steps. First, the individual pulse patterns for XV1
to XV8 are created by using the vertical pattern group registers.
Second, the vertical pattern groups are used to build the
sequences, where additional information is added. Third, the
readout for an entire field is constructed by dividing the field
into different regions and then assigning a sequence to ea
can contain up to seven different regions to
accommodate the different steps of the readout, such as high
speed line shifts and unique vertical line transfers. Up to six
different fields may be created. Finally, the MODE register al-
lows the different fields to be combined into any order for vari-
ous readout configurations.
