Group A/Group B Selection
The AD9923A has the flexibility to use two V-pattern groups in
a vertical sequence. In general, all vertical outputs use the same
V-pattern group during a sequence, but some outputs can be
assigned to a different V-pattern group. This is useful during
certain CCD readout modes.
The GROUPSEL register is used to select Group A or Group B
for each XV output (the LSB is XV1, the MSB is XV13). Setting
each bit to 0 selects Group A; setting each bit to 1 selects Group B.
If only a single V-pattern group is needed for the vertical
outputs, Group A is used by default (GROUPSEL = 0), and the
outputs use the V-pattern group specified by the VPATSELA
register.
If Group B flexibility is needed, the outputs set to 1 in the
GROUPSEL register use the V-pattern group selected by the
VPATSELB register. For example, Figure 38 shows outputs
XV12 and XV13 using a separate V-Pattern Group B to perform
special CCD timing.
Another application of the Group A and Group B registers is to
combine two VPAT groups for more complex patterns. This is
achieved by setting the TWO_GROUP register to 1. Figure 39
shows an example of this timing. When TWO_GROUP = 1,
the Group A and Group B toggle positions are both used. In
addition, length, starting polarity, and number of repetitions
are all determined by the appropriate registers for Group A
when TWO_GROUP = 1. Figure 40 shows the more complex
operation of combining Group A and Group B with repetition.
