NJW2311

Phase Shifter-less Wide Band FM IF Demodulator IC for Voice

Data Sheet

Features

  • Unnecessary External phase shifter (CD or IFT)
  • Auto IF detection (
    IF = 1.5MHz to 15MHz
    * S-curve characteristic cannot be obtained)
  • Demodulated Output Frequency Range (
    fmod = 20Hz to 100kHz
    * External parts modification : up to 300kHz)
  • Excellent electrical characteristics (
    SNR 80dB @fdev = 75kHz
    THD 0.015% @fdev = 75kHz)

General Description

NJW2311 is the IC which has the automatic IF detection of FM modulating signal of the 1.5MHz to 15MHz, that operates from 4.5V, and makes unnecessary such as the phase-shifter which was conventionally required as external parts. An IF amplifier, a FM demodulator and a low noise Op-amplifier are built in. Since high S/N ratio and low distortion characteristics are realized, it is the best for the various FM Receivers of wireless or wired Voice communications.

Applications

  • Wireless microphone (RF/IR)
  • Wireless headphone (RF/IR)
  • Intercom, Door phone
