LOW POWER NARROW BAND FM IF
MC3361N/D
DESCRIPTION
Outline Drawing
The MC3361 is designed for use in FM
dual conversion communication. It contains a
complete narrow band FM demodulation
system operable to less than 2.0V 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.
