470MHz INPUT 455kHz FMIF DEMODULATOR
GENERAL DESCRIPTION
PACKAGE OUTLINE
The
NJM2592
is a low-voltage, low-current FM IFdemodulator IC
with 455kHz(standard) IF frequency. It includes an oscillator, mixer,
limiting amplifier, quadrature detector,active filter, and FSK comparator.
The
NJM2592
also has a RSSI circuit and RSSI comparator for
carrier sense.
