Pin Function
Pin 20 can be used both as the First SIF IN and
inter/split switch pins.
In the case of inter carrier, connect pin 20 to GND.
When a sound saw filter is added, the matching
loss can be decreased by inserting L to neutralize
the IC input capacitance and saw filter output
capacitance.

VCC
Connect the decoupling capacitor as close as
possible.

Pins 23 and 24 are VIF input pins.
To reduce the loss of signal through a saw filter,
input registors are set to 2 kΩ.
VIF amplifier has three capacitive coupling
amplifiers, direct connection from a saw filter is
available.
