Product specification
Multistandard/dual channel TV FM
intercarrier sound demodulator
TDA9820
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.
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.
