LOW VOLTAGE/POWER NARROW BAND FM IF
INTRODUCTION
The S1T3361D 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.
16−DIP−300A
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 to 7.0V
16−SOP−225A
APPLICATIONS
• Cordless phone (for home usage)
• FM dual conversion communications equipment

Quad coil
In the above application circuit, 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.
