PIN EXPLANATION

Symbol

Function and Explanation

Equivalent Circuit

No.

OSC base

(bypass)

Internal oscillator consists in balance amplifier.

2 pin and 3 pin should be externally equiped

with tank resonater circuit in order to oscillate

with feedback loop.

OSC base

(feedback)

1 pin should be grounded through coupling

capacitor to 5 pF.

to OSC

buffer

amp.

3 pin is defined as open collector. This pin

should be coupled through resistor or chock coil

in order to adjust Q and be supplied voltage. In

case of abnormal oscillation, adjust its Q lower

to stabilize the operation.

REF

OSC

collector

(coupling)

V^CC

Supply voltage pin for the IC.

IF output

IF output pin. IF amplifier is designed as single-

end push-pull amplifier.

VCC

from IF

pre amp.

This pin is assigned for the emitter follower

output with 50 Ω constant resistive impedance

in wide band.

output

GND

GND pin for the IC.

RF input 1

(bypass)

7 pin and 8 pin are inputs for mixer designed as

double balanced type.

VCC

to IF

Either pin can be assigned for input and another

for ground.

amp.
