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.
