PLL-SPLIT VIF/SIF IC
The input impedance is 2kΩ.

driving current : 1mA
The FM detector can respond to the 4.5MHz intercarrier
signal without an adjustment and external components by
adopting the PLL technique.
The output DC voltages of 4.4V0-P and 2.4V0-P are in the
Vcc of 9V and 5V, respectively.
Since its output frequency is more than 100kHz in no
loading condition, it can also respond to the multi audio
broadcasting.

The frequency response of the audio output is set by the
external capacitor of pin 12.
[Pin 11 output]
In the case of 0.1µF, the cut-off frequency is 35Hz.
[FM mod. frequency]
100kHz
Connecting series resistor to the capacitor above, can
reduce an audio output amplitude.
