NJM2597 - 455kHz INPUT FM IF DEMODULATOR

Description

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.

Features
