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.
