conserves register memory if the four separate V-patterns are
not needed.
Note that when CONCAT_GRP is enabled, Group A settings
are used only for start position, polarity, length, and repetitions.
All toggle positions for Group A, Group B, Group C, and Group D
are combined together and applied using the settings in the
VSTARTA, VPOL_A, VLENA, and VREPA registers.
Special Vertical Sequence Alternation (SVSA) Mode
The AD9992 has additional flexibility for combining four
different V-pattern groups in a random sequence that can be
programmed for specific CCD requirements. This mode of
operation allows custom vertical sequences for CCDs that
require more complex vertical timing patterns. For example,
using the special vertical sequence alternation mode, it is
possible to support random pattern concatenation, with
additional support for odd/even line alternation.
Figure 39 illustrates four common and repetitive vertical pattern
segments, A through D, that are derived from the complete vertical
pattern. Figure 40 illustrates how each group can be concatenated
in an arbitrary order.
To enable the SVSA mode, write the VSEQALT_EN bit,
Address 0x20 Bit 13, equal to 0x01. The location of the VALTSEL
registers is shared with the VPAT registers for XV24. When
SVSA mode is enabled, the VALTSEL register function is
selected.
To create SVSA timing, divide the complete vertical timing
pattern into four common and repetitive segments. Identify
the related segments as VPATA, VPATB, VPATC, or VPATD.
Up to four toggle positions for each segment can be programmed
using the V-pattern registers.
Table 15 shows how the segments are specified using a 2-bit
representation. Each bit from VALTSEL0 and VALTSEL1 is
combined to produce four values, corresponding to Pattern A,
Pattern B, Pattern C, and Pattern D.

When the entire pattern is divided, program VALTSEL0 (even
and odd) [17:0] and VALTSEL1 (even and odd) [17:0] so that
the segments are concatenated in the desired order. If separate
odd and even lines are not required, set the odd and even registers
to the same value. Figure 41 illustrates the process of using six
vertical pattern segments that have been concatenated into a small,
merged pattern.
Program the register VREPA_1 to specify the number of segments
to concatenate into each merged pattern. The maximum number of
segments that can be concatenated to create a merged pattern is
18. Program VLENA, VLENB, VLENC, VLEND to be of equal
length. Finally, program HBLK to generate the proper H-clock
timing using the procedure for HBLK Mode 2 described in the
HBLK Mode 2 Operation section.
It is important to note that because the FREEZE/RESUME registers
are used to specify the VALTSEL registers, the VALT_MAP
register must be enabled when using the special VALT mode.

registers.
