PLL-SPLIT VIF/SIF IC

The input impedance is 2kΩ.

Pin 11 (AF OUTPUT)

11

internal

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.

Pin 12 (AUDIO F/B)

50kΩ

Terminal voltage : 3.0V

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.
