50MHz INPUT MIXER AND 450kHz FM IF DEMODULATOR IC
GENERAL DESCRIPTION
PACKAGE OUTLINE
The NJM2593
is a wide-operating voltage, low-current
FM IF demodulator IC with 450kHz(standard) IF frequency.
It includes an oscillator, mixer, limiting amplifier, quadrature
detector, active filter, and FSK comparator.
The NJM2593
also has a RSSI circuit and RSSI comparator
for carrier sense.
