Description
Those pins are connected to the external
parts of an oscillating circuit.
The oscillator is an internally-biased Colpitts
type with the collector, base, and emitter
connections at Vcc, pins 1 and 2
respectively.
Mixer output pin. Connect a 455kHz ceramic
filter between this pin and the IF IN pin.
Vcc pin.
Input pin for the IF limiter amplifier.
Connection pin of the bypass capacitor for
the IF limiter amplifier. Connect a capacitor of
about 0.047µF between this pin and ground
(or Vcc).
Connection pin of the bypass capacitor for
the IF limiter amplifier. Connect a capacitor of
about 0.047µF between this pin and ground
(or Vcc).
Connected to a quadrature detector phase
shifter.
