AD9923A
VERTICAL TIMING GENERATION
The AD9923A provides a very flexible solution for generating
vertical CCD timing; it can support multiple CCDs and different
system architectures. The 13-phase vertical transfer clocks, XV1 to
XV13, are used to shift lines of pixels into the horizontal output
register of the CCD. The AD9923A allows these outputs to be
individually programmed into various readout configurations,
using a four-step process as shown in Figure 35.

1.
Use the vertical pattern group registers to create the individual
pulse patterns for XV1 to XV13.
2.
Use the V-pattern groups to build the sequences and add more
information.
3.
Construct the readout for an entire field by dividing the field
into regions and assigning a sequence to each region. Each
field can contain up to nine regions to accommodate different
steps, such as high speed line shifts and unique vertical line
transfers, of the readout. The total number of V-patterns,
V-sequences, and fields are programmable and limited by the
number of registers. High speed line shifts and unique vertical
transfers are examples of the different steps required for
readout.
4.
Use the MODE register to combine fields in any order for
various readout configurations.
CREATE THE VERTICAL PATTERN GROUPS,
UP TO FOUR TOGGLE POSITIONS FOR EACH OUTPUT.
