Pin 14 (RF AGC OUT)
A current mode output is available in the reverse AGC
operation.

Note: Connecting a nonpolarity capacitor of 1 F between pin 14 and pin 18 improves AGC operating
speed.
In that case, the capacitors between pin 14/pin 18 and ground should be removed.
Pin 15 (GND)

It is GND pin except for SIF.

It should be designed considering careful impedance
matching with the SAW filter.

Pin 18 (RF AGC DELAY)
An applied voltage to the pin 18 is for changing a RF AGC
delay point.
VCC
In the 3-in-1 type application, the regulated output from the
regulator is suitable for a power supply (VCC) to it, because
there may be difference between the tuner and main board
18
supply.
TV tuner, VIF demodulator and RF modulator are togetherin
one package.
