Power supply pin.
This pin should be externally equipped
with bypass capacitor to minimize
ground impedance.
Signal input pins to AGC amplifier.
This pin should be coupled with
capacitor for DC cut.
Gain control pin.
This pin’s bias govern the AGC output
level.
Recommended to use AGC voltage with
externally resister (example: 1 kΩ).
Ground pin.
This pin should be connected to system
ground with minimum inductance.
Ground pattern on the board should be
formed as wide as possible.
Signal output pins of video amplifier.
This pin should be coupled with
capacitor for DC cut.
Ground pin.
This pin should be connected to system
ground with minimum inductance.
Ground pattern on the board should be
formed as wide as possible.
All ground pins must be connected
together with wide ground pattern to
decrease impedance difference.
