MC3357P, Low Power FM IF Receiver IC, DIP-16

The MC3357P is a low power FM intermediate frequency (IF) receiver integrated circuit, tailored for voice communication scanning receivers. It integrates multiple functions—including an oscillator, mixer, limiting amplifier, quadrature discriminator, active filter, squelch, scan control, and mute switch—into a single chip, thereby reducing the need for external components and streamlining the design process.

Operating with a typical drain current of 3.0 mA at a 6.0 V supply voltage, the MC3357P is ideal for battery-operated devices. Its high sensitivity, with an input limiting voltage of 5.0 µV, ensures reliable performance even in environments with weak signals. The IC supports a supply voltage range from 4.0 V to 8.0 V, offering versatility across various applications.

Encased in a DIP-16 package, the MC3357P is designed for through-hole mounting, simplifying integration into standard PCB layouts. This makes it a preferred choice for designers seeking an efficient and compact solution for FM IF receiver applications.
