CROCK

protection operating time of about 2.1 seconds can be set

by connecting a capacitor (of about 0.047 µF) between this

pin and ground.

VCC

Setting for the charge current used for the VCO circuit C pin

36

R

Connect a resistor between this pin and ground. The value

of that resistor must not be lower than 2.7 kΩ.

VCC

VCO oscillator connection. This pin sets the VCO

frequency.

37

C

Connect a capacitor between this pin and ground.

Set the value of the capacitor so that the oscillator

frequency does not exceed 1 MHz.
