PIN DESCRIPTION
PIN NO. 1 SYMBOL FUNCTION AND APPLICATION Internal oscillator consists of a balanced amplifier. Pins 2 and 3 should be externally equipped with a tank resonator circuit in order to oscillate with feedback loop. Pin 1 should be grounded through a coupling capacitor (~10 pF). Pin 3 is an open collector. This pin should be coupled through resistor or choke coil in order to adjust Q and connect to supply voltage. In case of unstable oscillation, lowering the Q will help to stabilize the operation. Supply voltage pin for the IC.
