MC3361BP
LINEAR INTEGRATED CIRCUIT
LOW VOLTAGE/POWER
NARROW BAND FM IF
DESCRIPTION
The UTC MC3361BP is designed for use in FM dual conversion
communication. It contains
a
complete narrow band FM
demodulation system operable to less than 2.5V supply voltage. This
low-power narrow-band FM IF system provides the second
converter, second IF, demodulator. Filter Amp and squelch circuitry
for communications and scanning receivers.
FEATURES
*Low power consumption (4.0mA typ. at Vcc=4.0V)
*Excellent input sensitivity
(-3dB limiting, 2.0μVrms typ.)
*Minimum number of external components required.
*Operating Voltage: 2.5~7.0V
APPLICATIONS
*Cordless phone (for home use)
*FM dual conversion communications equipment

LINEAR INTEGRATED CIRCUIT
APPLICATION CIRCUIT
In the above typical application, the audio signal is recovered using a conventional quadrature FM detector. The
absence of an input signal is indicated by the presence of noise above the desired audio frequencies. This “noise
band: is monitored by an active filter and a detector. A squelch trigger circuit indicates the presence of noise (or a
tone) by an output which can be used to control scanning. At the same time, an internal switch is operated which can
be used to mute the audio.
