THE POLARITY OF H1 DURING BLANKING IS PROGRAMMABLE (H2 IS OPPOSITE POLARITY OF H1)
Figure 11. HBLK Masking Control
Horizontal Sequence Control
The AD9847 uses sequence change positions (SCP) and sequence
pointers (SPTR) to organize the individual horizontal sequences.
Up to four SCPs are available to divide the readout into four
separate regions, as shown in Figure 12. The SCP 0 is always
hard-coded to line 0, and SCP1–3 are register programmable.
During each region bounded by the SCP, the SPTR registers
designate which sequence is used by each signal. CLPOB, CLPDM,
PBLK, and HBLK each have a separate set of SCP. For example,
CLPOBSCP1 will define Region 0 for CLPOB, and in that region
any of the four individual CLPOB sequences may be selected
with the CLPOBSPTR registers. The next SCP defines a new
region, and in that region each signal can be assigned to a different
individual sequence. The sequence control registers are summarized
in Table VI.
UP TO FOUR INDIVIDUAL HORIZONTAL CLAMP AND BLANKING REGIONS MAY BE
PROGRAMMED WITHIN A SINGLE FIELD, USING THE SEQUENCE CHANGE POSITIONS.
