7. Adjustment of Black-Level S/H Response Frequency Characteristics
The CR time constant that is used for sampling/hold (S/H) at the black level can be adjusted by changing the
register settings, as shown in table 6.

BLKC
C
Recommendation value of C is 1000 pF
The SHAMP frequency characteristics can be adjusted by changing the register settings
and the C4 value of the external pin.
The settings are shown in table 7.
Values other than those shown in the table 7 cannot be used.
