Equivalent circuit
1
P/S ratio becomes large when
the capacitance connected be-
tween pin and GND increases.
2 k
Pin to control RF OSC.
Oscillation of RF becomes
3
unstable when capacitance
10 k
connected between pin and
GND is too small.
Reference bias source of
oscillator. Sound buzz appears
to decrease in sense of hear-
6.2 k
ing when capacitance is con-
nected between pin and GND
5
to cut AC signal. Oscillation
frequency is determined by
the external tank circuit.
Reference oscillator for
4.5 MHz sound modulator.
Typical DC voltage is almost
same as GND potential. If
DC level of sound input sig-
nal is GND potential, an ex-
ternal coupling capacitor is
not necessary. The circuit
configuration which is de-
signed to minimize the volt-
age variation at power sup-
ply on makes less pop noise.
