Note 1 : IF C9, C10 are polarized capacitors, refer to “VCO Stop Method ™” shown below
Note 2 : For loop filter constants (C9, C10, R8), refer to 4. Capture range and PLL loop filter constants on page 5 and set
these constants to the optimum values for the input pilot level.

Remarks
Proper Cares in Using IC
1. VCO stop method
One of the following is used to stop VCO. The monaural mode is forced to be entered at the time of VCO stop.
(1) VCO stop method ¡
(a) For loop filter capacitors (C9, C10 in Fig. 1), use one of the following.
(1) Non-polarized capacitor
(2) Polyester film capacitor
[Reason] When in the VCO stop mode, external voltage VS causes an
unpolarized voltage of approximately 1.5V to be developed
across pins 14 and 15.
(b) Setting of external voltage VS and limiting resistor RS.
The relation between VS and RS is shown in Fig. 9. When in the VCO stop mode, the value of RS must be set so
that the voltage on pin 11 is within the specified range (min=5.5V, max=VCC–3V). For example, it is seen from
Fig. 9 that the value of limiting resistor RS is approximately 4.2kΩ when the voltage on pin 11 is set to 6V at
VS=12V.
