SL5018/P
LOW POWER NARROW BAND FM IF
Description
The SL5018/P 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.
