Description
This pin offset adjusts the
CLPDRV black level when
the CXA1690 satisfies the
operating conditions for the
camera signal system
54k (when CAMVI is High and
PBREC is Low).
VCC: approx. 500mV
20/50 VCC: approx.
–50mV
Preset: approx. 70mV

OFFSET voltage (V)
Pulse input for BLK
(active: Low). This pin
functions only when
CAMVI is High and
PBREC is Low, and
calibrates the black
level of the AGC
output waveform.
When the pulse is low,
the DRVOUT potential
is forced to 2V.
High-speed S/H pulse
input for CAMSH
(active: Low).
High-speed S/H pulse
input for SH1
(active: Low).
High-speed S/H pulse
input for SH2 and SH3
(active: Low).
