NJW2311 Overview
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.
Key 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 SNR 80dB @fdev = 75kHz THD 0.015% @fdev = 75kHz
