Power supply pin. This pin should be externally
equipped with bypass capacitor to minimize
ground impedance.
Signal input pins of AGC amplifier.
Gain control pin. This pin's bias govern the
AGC output level.
Minimuim Gain at V
Maximum Gain at V
Recommended to use a 0 to 5 V AGC range
for the system and divide this voltage through
a resistive bridge (see evaluation board).
This helps make the AGC slope less steep.
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
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.
