DESCRIPTION
Decoupling capacitor pin of the
blanking offset control D/A
converter. Connect to the GND1 via
a capacitor.
Blanking pulse input pin.
The output of the AGCOUT pin is
blanked when low. The blanking
level can be controlled by the serial
interface.
Power supply pin of the fl/H3 and
OPB clamp circuits.
GND pin of the fl/H3 and OPB
clamp circuits.
Power supply pin of the output
buffer circuit connected to the
AGCOUT pin.
Signal output pin of the AGC.
Connect to the ADIN pin via a
capacitor.
GND pin of the output buffer circuit
connected to the AGCOUT pin.
Decoupling capacitor pin of the
AGC gain control D/A converter.
Connect to the GND1 via a
capacitor.
