Ground pin of oscillator amplifier.

Buffer amplifier, oscillator output.

Base Pin of oscillator. Connected

to 14 pin through a capacitor.

Collector pin of oscillator.

Connected to 15 pin through

capacitor. Oscillator frequency

bandwidth is dependent on this

capacitor. This pin should be connected

to VCC through a 150 Ω resistor.

Collector pin of oscillator. Connected to

14 pin through capacitor. This pin should

be connected to VCC through a 150 Ω

resistor.

Base pin of oscillator. Connected to

15 pin through capacitor. Assemble LC

resonator between 13 pin and 16 pin

through 2 pF capacitor to oscillate.

Output pin of oscillator.

This pin is assigned for emitter

follower output.

Ground pin of oscillator amplifier,

buffer amplifier, oscillator output.

Power supply pin of oscillator output.
