SYMBOL FUNCTION AND APPLICATION 1 OSC Base (Bypass) 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. 2 OSC Base (Feedback) 3 OSC Collector (Coupling) 4 VCC EQUIVALENT CIRCUIT 3 2 To OSC buffer amp 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. 1 Vcc VREF Supply voltage pin for the IC. Vcc 5 IFOUT IF output pin. IF amplifier is designed as a singleended push-pull amplifier. This pin is an emitter follower output with a wideband 50 Ω impedance. 6 GND GND pin for the IC.
