MC3359 Datasheet HIGH GAIN LOW POWER FM IF

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: Order this document by MC3359/D Low Power Narrowband FM IF . . . includes oscillator, mixer, limiting amplifier, AFC, quadrature discriminator, op/amp, squelch, scan control, and mute switch.

Key Features

  • e 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.
