4. Forced monaural mode
To provide the forced monaural mode, pin 16 is con-
nected to GND through a resistor of 10k
. In this case,
VCO oscillation does not stop.
FM/AM mode changeover
(1) How to change over
Changeover is performed by externally applying volt-
age to pin 10.
FM
→
AM changeover : Apply a voltage of 4.3V to
V
CC
–2 (not exceeding 10V) to pin.
AM
→
FM changeover : Apply a voltage of 0.5V or less
to pin 10.
Fig. 9 shows the relation between the voltage on pin 10
and the flow-in current.
(2) Muting in the changeover mode
Muting is turned ON for a certain period of time fixed
by external capacitor C6 in the FM
→
AM or AM
→
FM changeover mode (muting in the changeover mode).
Fig. 10 shows the relation between the muting time in
the chageover mode and C6.
(3) VCO oscillation stop in the AM mode
By externally applying a specified voltage to pin 10 to select the AM mode, VCO oscillation stops automatically and
the monaural mode is forced to be entered.
Muting function
(1) How to turn ON/OFF muting
Muting is turned ON/OFF by externally applying voltage to pin 15.
Muting ON :
Apply a voltage of 3.5V to V
CC
–3V to pin 15.
Muting OFF : Apply a voltage of 0.3V or less to pin 15.
Fig. 9 shows the relation between the voltage on pin 15 and the flow-in current.
(2) Hysteresis characteristic
Muting ON/OFF is allowed a hysteresis of approximately 6dB to prevent malfunction attributable to ripple in-
cluded in the IF meter output, muting drive output.
(3) Forced monaural in the muting mode
By externally applying a specified voltage to pin 15 to select the muting mode, the forced monaural mode is
automatically entered.
