Description
Ground.
Common for SCF section. Connect to decoupling capacitor.
Signal input. Input a frequency-modulated signal (composite signal) at 200 to 300 mVrms.
When inputting 76 kHz only, the input sensitivity is 4 mVrms or less.
MSK output (CMOS output.)
Limiter reference pin. Form an LPF with the 10 k
internal resistor and an external
capacitor.
3.6 MHz clock input. Because the DC bias is output by the limiter amplifier input, the clock
is input with capacitor coupling.
Power supply
Test pin. Leave open.

Notes on usage:
(1) When using this IC, leave pins 4 to 9 and pin 13 open.
(2) The clock is connected to pin 12 from the decoder (LC72700) clock output pin through a 100 pF capacitor. In addition, by
inserting a resistor in the clock line, it is possible to dampen the rising and falling edges, reducing spurious radiation.

Note : Pins 4 through 9 and pin 13 must be left open.
