描述 Description

GENERAL DESCRIPTION
The TDA9820 is a monolithic, integrated, multistandard TV FM intercarrier sound demodulator for all FM standards. The circuit contains two separate FM demodulators using Phase Locked Loop (PLL) reference frequency generation. The circuit requires a minimum number of external components.FEATURES
? Multistandard application for sound standards M, B/G, I and D/K
? Two alignment-free PLL FM demodulators
? Four-input source selector for one of the two FM demodulators
? Automatic second sound carrier mute
? Mono and dual channel application
? Low power consumption
? Few external components required.
