PIN NAME

FUNCTION AND APPLICATION

VOLTAGE (V) VOLTAGE (V)

RF input

—

0.77

RF input for mixer. This port

is low impedance.

GND

0

—

This ground pin must be

connected to the system

ground with minimum

inductance. Ground pattern

on the board should be

formed as wide as possible.

Track length should be kept as

short as possible.

OSC Emitter

—

OSC Base

—

0.19

Emitter, base pins of internal

transistor for oscillator.

These pins should be exter-

nally equipped with resonator

circuit of X’tal or LC.

VCC

1.0 to 2.0

—

Supply voltage pin.

Connect bypass capacitor (eg

1 000 pF) to minimize ground

impedance.

IF Output Same bias

—

IF output pin from mixer.

as VCC

This pin is designed as open

through

collector and should be

external

equipped with inductor (L)
