Low Power
Narrowband FM IF
The MC3371 and MC3372 perform single conversion FM reception and
consist of an oscillator, mixer, limiting IF amplifier, quadrature discriminator,
active filter, squelch switch, and meter drive circuitry. These devices are
designed for use in FM dual conversion communication equipment. The
MC3371/MC3372 are similar to the MC3361/MC3357 FM IFs, except that a
signal strength indicator replaces the scan function controlling driver which is
in the MC3361/MC3357. The MC3371 is designed for the use of parallel LC
components, while the MC3372 is designed for use with either a 455 kHz
ceramic discriminator, or parallel LC components.
These devices also require fewer external parts than earlier products. The
MC3371 and MC3372 are available in dual–in–line and surface mount
packaging.
Wide Operating Supply Voltage Range: VCC = 2.0 to 9.0 V
