NTE1489 Overview
The NTE1489 is a silicon monolithic integrated circuit in a 16 Lead DIP type package designd for use as an FM multiplex demodulator for high class stere FM tuners. As the IC adopts a PLL (Phase Lock Loop) system, plexity of contol is usually experienced when using conventional external coil is eliminated and the demodulator can easily be constructed by simply controlling the external semi fixed potentiometer....
