Pin 14 (RF AGC OUT)  
A current mode output is available in the reverse AGC  
operation.  
The maximum  
outflow current  
is 0.2 mA.

(IF input)  
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)  
15  
It is GND pin except for SIF.  
Pin 16, Pin 17 (VIF IN)

It should be designed considering careful impedance  
matching with the SAW filter.  
Terminal voltage  
: 1.45 V  
1.2 k  
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.
