455kHz INPUT FM IF DEMODULATOR
GENERAL DESCRIPTION
PACKAGE OUTLINE
The
NJM2590 and NJM2597
are low current FM IF demodulator
ICs with 455kHz IF input, which operate from 1.6V supply.
The
NJM2590/97
contain the minimum functions required to
FM IF demodulator, that is, IF amplifier, quadrature detector,
LPF amplifier, FSK comparator, RSSI, and RSSI comparator.
It offers unmatched design flexibility.
