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