SYMBOL

Function and Explanation

Equivalent circuit

OSC base

(bypass)

2.9

Internal oscillator consists in balance

amplifier. 2 pin and 3 pin should be

externally equipped with tank resonator

circuit in order to oscillate with feedback

loop.

VCC

OSC base

(feedback)

2.9

5.0

1 pin should be grounded through

coupling capacitor to 0.5 pF.

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.

OSC

collector

(coupling)

V^CC

5.0

Supply voltage pin for the IC.

IF output

µPC2721

In µPC2721, IF amplifier is designed as

single-end push-pull amplifier.

µPC2721

2.9

This pin is assigned for the emitter follower

output with 50 Ω constant resistive

impedance in wide band.

µPC2722

In µPC2722, IF amplifier is designed as

balance amplifier.

µPC2722

5.0

This pin is assigned for the open collector

output with high impedance dependent on

external inductance.

GND

0.0

2.4

GND pin for the IC.

RF input 2

(bypass)

7 pin and 8 pin are inputs for mixer

designed as double balanced type. Either

pin can be assigned for input and another

for ground.

RF input 1

2.4
